Wake wazibuza ukuthi imizimba yethu ithumelana kanjani imiyalezo emincane yokulwa nezifo nokusizana? Kunezingxenye zemizimba yethu ezisebenza njengezithunywa ezincane eziyimfihlo. Ama-Cytokine ayiqembu lamakhemikhali enza umsebenzi okhethekile kangaka. Namuhla, sizoxoxa ngalezi zithunywa ezincane kodwa ezibaluleke kakhulu.

Ayini ngempela ama-cytokine?

Kalula nje, ama-cytokine awuhlobo lweprotheni. Afana nezithunywa zamakhemikhali ezidlulisela ulwazi ohlelweni lwethu lokuzivikela komzimba . Cabanga ngohlelo lwethu lokuzivikela komzimba njengebutho elivikela izwe. Leli butho linamagatsha ahlukene, amasosha. Ngubani othumela la masosha (okungukuthi amasosha omzimba) imiyalezo efana nokuthi, "Nansi isitha!" "Hamba lapha ulwe!" "Zivikele kanje!"? Yilokho okwenziwa yilawa ma-cytokine . Lapho amagciwane anjengegciwane, amagciwane, amabhaktheriya, noma izinto ezibangela ukungezwani komzimba zingena emizimbeni yethu, lawa ma-cytokine atshela amangqamuzana ethu omzimba ukuthi "aqale ukusebenza, alwe nalaba bahlaseli." Akukhona lokho kuphela, kodwa lawa ma-cytokine asiza ukugcina uhlelo lwethu lokuzivikela komzimba lusebenza kahle futhi luhambisana, ngisho noma kungekho songo emizimbeni yethu. Njengoba nje imiyalezo ishintshaniswa ukuze ihhovisi lethu liqhubeke kahle.

Yiziphi izinhlobo zama-cytokine ezikhona?

Kunezinhlobo eziningi ezahlukene zamalungu alo mndeni wezithunywa ezibizwa ngokuthi ama-cytokine. Zonke zitshela amangqamuzana omzimba ukuthi aye kuphi nokuthi enzeni. Kodwa kunezinhlobo eziningana, kuye ngemisebenzi yazo ethile. Ake sibheke ezimbalwa zezinhlobo eziyinhloko.

Ama-Chemokine: Lawa “ama-guider.” Afana ne-GPS. Yiwo aqondisa amangqamuzana omzimba endaweni yokutheleleka, ewatshela ukuthi, “Wozani ngapha.”
Ama-Interferons: Igama lawo lisho ukuthi “ukuphazamisa.” Kusho ukuthini ukuphazamisa? Asebenza ngokuvimbela amagciwane ukuthi angangeni emaseli ethu futhi enze amagciwane engeziwe ('ukuziphindaphinda'). Kufana nokubeka uphawu lwamagciwane oluthi, “Akusekho ukuya lapha!”
Ama-Interleukin: Leli gama lisuselwa emagameni athi "inter" (phakathi) kanye nelithi "leukocyte" (iseli elimhlophe legazi). Ngaphambilini kwakucatshangwa ukuthi la makhemikhali axhumana kuphela phakathi kwamangqamuzana amhlophe egazi. Kodwa-ke, manje sekutholakale ukuthi akhiqizwa nangamanye amangqamuzana nokuthi axhumana naphakathi kwamangqamuzana angewona amhlophe egazi.
I-Tumor Necrosis Factor (TNF): Lokhu kuzwakala njengegama elibi, akunjalo? Umsebenzi walo oyinhloko ukwenzaIlawula ukuvuvukala , okusho ukuvuvukala nokubomvu. Iphinde inikeze amaseli omzimba amandla okubhubhisa amaseli esimila .
Izinto Ezivuselela Ikholoni (CSF): Lezi zifana "nabaphathi befektri yamaseli" emzimbeni wethu. Ngoba, kukhona uhlobo olukhethekile lweseli olubizwa ngokuthi amaseli egazi aqinile (HSC) . Lawa maseli angenza zonke izinhlobo zamaseli egazi njengeeseli ezimhlophe zegazi, amaseli abomvu egazi, nama-platelet. Le "nqubo yokukhiqiza" ( i-Hematopoiesis ) isizwa yile "CSF", okungukuthi, itshela amaseli egazi ukuthi "akhiqize lolu hlobo lweseli". Isibonelo, " i-G-CSF " isiza ekwenzeni uhlobo lweseli elimhlophe legazi elibizwa ngokuthi "i-Neutrophil" . Lawa ma-neutrophil abaluleke kakhulu ekulweni nokutheleleka.

Amanye ama-cytokine aqanjwe ngohlobo lweseli eliwakhiqizayo.
Ama-lymphokine: Ngoba akhiqizwa uhlobo lweseli elimhlophe legazi elibizwa ngokuthi ama-lymphocyte.
Ama-monokine: Ngoba akhiqizwa uhlobo lweseli elimhlophe legazi elibizwa ngokuthi ama-monocyte.
Yiluphi usizo olunikezwa ama-cytokine emizimbeni yethu?
Uma sikhuluma ngama-cytokine, abantu abaningi bacabanga ngokuvuvukala . Uma sicabanga ngokuvuvukala, sicabanga ngokuvuvukala okucasulayo kanye nokubomvu okwenzeka ngesikhathi sokugula noma ukungezwani komzimba. Kodwa ukuvuvukala empeleni kuwuphawu lokuthi amangqamuzana omzimba wethu alwa nabahlaseli noma aphulukisa izicubu ezilimele.
Cabanga nje uma usika umunwe wakho, indawo iyavuvukala futhi ibe bomvu, akunjalo? Lokho ukuvuvukala. Lokho kusho ukuthi ama-cytokine athunyelwa lapho, athi, "Kunenkinga lapha, woza uzobheka, bese upholisa inxeba," bese kulethwa amangqamuzana afanele aqale ukusebenza.
Ngakho-ke, ama-cytokine afana nezithunywa zamakhemikhali ezitshela amangqamuzana ukuthi "aziphatha kanjani." Ngokuyinhloko abonisa izinto ezifana nalezi:
Ukusebenza kweseli: Kutshela amaseli ukuthi aye kuphi nokuthi enzeni. Isibonelo, kuqondisa amaseli omzimba endaweni yokutheleleka ukuze alwe namagciwane lapho. Kuphinde kubonise ukwandisa noma ukunciphisa izinqubo ezihlobene nokuvuvukala.
Ukwehlukaniswa kwamaseli:Lokhu kufana nesikole sokuqeqesha. Bathatha amangqamuzana angakavuthwa bese bewaqeqesha ukuba abe “lolu uhlobo lweseli ofuna ukuba yilo uma ukhula.” Isibonelo, bathatha iseli elincane bese beliguqula libe iseli legazi elimhlophe elingalwa nokutheleleka.
Ukwanda kwamaseli: Lokhu kusho "ukwenza abantu abaningi bafane nawe." Kufana nokwenza ikhophi. Isibonelo, uma udinga amaseli egazi amhlophe engeziwe ukuze ulwe nokutheleleka, utshela amaseli akho amhlophe egazi akhona ukuthi "wenze abantu abaningi bafane nawe."
Akukhona lokho kuphela, kodwa ngezinye izikhathi ama-cytokine aphinde atshele amangqamuzana omzimba wethu ukuthi "akhiqize ama-cytokine engeziwe." Bese impendulo yokuvuvukala iyanda kakhulu.
Uyini umehluko phakathi kwama-cytokine akhuthaza ukuvuvukala kanye nama-cytokine alwa nokuvuvukala?
Uma amasosha ethu omzimba esebenza kahle, ama-cytokine abangela ukuvuvukala uma kudingeka ukuze alwe nabahlaseli futhi aphulukise izicubu. Bese bethi, "Kulungile, sekwanele, sekwanele," bese benciphisa futhi bamise ukuvuvukala. Kufana ne-accelerator (i-gas pedal) kanye ne-brake emotweni.
Ama-cytokine akhuthaza ukuvuvukala: Lawa “ama-gas pedals.” Laba ngabantu abakhombisa ukuthi ukuvuvukala kuqala futhi kwanda. Lapho isitha singena emizimbeni yethu, bathi, “Wonke umuntu, lungiselelani impi!”
Ama-cytokine alwa nokuvuvukala: Lawa "amabhuleki". Lawa yiwo abonisa ukuthi kufanele kumiswe futhi kuncishiswe ukuvuvukala . Ngoba, uma ukuvuvukala kwanda kakhulu, kungalimaza nezicubu ezinhle emzimbeni wethu. Lawa yiwo avimbela lokho.
Uma sikhuluma iqiniso, ukuyeka ukuvuvukala kubaluleke kakhulu njengokukuqala. Ukuvuvukala kakhulu kungaholela ezimpawini ezingakhululekile, ezifweni zesikhathi eside, futhi ngezinye izikhathi, uma kungelashwa, kungaba yingozi empilweni.
Lawa ma-cytokine asebenza kanjani?
Lokhu kwenzeka ngendlela elula kakhulu. Cabanga nge-cytokine njengesihluthulelo , futhi kukhona i-'receptor' esiseleni ehambisana naleyo khiye. Lapho i-cytokine (isihluthulelo) ihamba futhi ingena kuleyo 'receptor' ekuleyo seli, leyo seli ithola umlayezo othi "Yini okufanele uyenze?". Bese lelo seli lisebenza ngokwalowo myalezo. Ake sibheke isibonelo. Uma elinye lamaseli ethu omzimba libona into eyingozi, njengegciwane, ngaphakathi emzimbeni, lelo seli likhipha i-cytokine. Le cytokine ihamba ngegazi noma ngezicubu bese ithola iseli eline-'receptor' elihambisana nayo. Lapho i-cytokine ibopha kuleyo 'receptor', iseli elamukela lowo myalezo lithola umlayezo. Mhlawumbe lelo seli lizoya lapho igciwane likhona bese liqala ukulihlasela. Noma, lizoqinisa ukuzivikela kwalo ukuvimbela igciwane ukuthi lingangeni. Ama-Cytokine angathumela imiyalezo esiseleni esiwakhiphe, kumaseli aseduze, noma ngisho nasemaseli akude.
Ukuthumela imiyalezo kuseli yayo (`i-Autocrine signaling`):I-cytokine ibopha ku-receptor esesiseleni esiyikhiphile.
I-Paracrine signaling: ibopha kuma-receptor kumaseli aseduze.
Ukubonakaliswa kwe-Endocrine: Ama-Cytokine abopha kuma-receptor kumaseli akude kakhulu neseli eliwakhiphe.
Kukhona amangqamuzana kuyo yonke imizimba yethu anama-cytokine `receptors. Eqinisweni, izitho eziningi emizimbeni yethu ziqukethe amangqamuzana anala ma-`receptors.' Yingakho ukuvuvukala kungenzeka noma kuphi.
Avelaphi ama-cytokine? Ubani owawenzayo?
Ama-cytokine avame kakhulu emzimbeni wethu akhiqizwa amangqamuzana omzimba , okungamaseli amhlophe egazi (ama-leukocyte). Amanye alawa ahlanganisa:
Ama-Macrophage
Amaseli e-dendritic
Ama-lymphocyte (ama-lymphocyte e-T ne-B)
Ama-monocyte
Ama-neutrophil
Ama-Basophil
Ama-Eosinophil
Amaseli e-mast
Kodwa akuwona amangqamuzana omzimba kuphela, kodwa nezinye izinhlobo eziningi zamangqamuzana emzimbeni wethu zingakhiqiza ama-cytokine. Nazi izibonelo ezimbalwa:
Amaseli e-Endothelial: Amaseli angaphakathi kwemithambo yegazi yethu.
Amaseli e-Epithelial: Amaseli ahambisana nezitho zethu.
Ama-Fibroblast: Amaseli atholakala ezicutshini ezixhumeneyo.
Amaseli e-Stromal: Olunye uhlobo lweseli olutholakala ezicutshini ezixhumeneyo.
Amaseli eSchwann: Amaseli azungeze amaseli ezinzwa (ama-neurons).
Uhlobo olufanayo lwe-cytokine lungakhiqizwa izinhlobo ezahlukene zamaseli.
Yiziphi izifo ezingahlotshaniswa nama-cytokine?
Ama-Cytokine abalulekile ohlelweni lwethu lokuzivikela komzimba, futhi ahlotshaniswa nezifo eziningi esingazithola. Ngokuvamile, ama-cytokine asiza ekusigcineni singenazo izifo. Kodwa-ke, ngezinye izikhathi uhlelo lwethu lokuzivikela komzimba lungakhiqiza ama-cytokine amaningi kakhulu. Lokhu kungaba ukuphendula ekuthelelekeni noma njengengxenye yokwelashwa okufana ne-immunotherapy . Lokhu kubizwa ngokuthi i-cytokine release syndrome (CRS) noma i-cytokine storm . Lokhu kungabangela izimpawu ezahlukahlukene ezithinta izinhlelo eziningi zomzimba wethu. Uma kungelashwa, lesi simo singasongela impilo. Uma kunama-cytokine amaningi kakhulu, impendulo yokuvuvukala iyanda. Lokhu kuvuvukala okweqile kungalimaza izicubu, okuholela ezifweni ezifana nalezi:
Izifo ezizenzakalelayo: Yilapho amasosha ethu omzimba ehlasela ngephutha amangqamuzana ethu aphilile.
Izinkinga ze-Metabolic:Izinkinga ezihlobene nokuguqulwa kwe-metabolism, inqubo imizimba yethu eguqula ngayo ukudla kube amandla futhi isuse imfucuza.
Umdlavuza
I-Sepsis: Lokhu kwenzeka lapho impendulo yomzimba yokuvuvukala iba nzima kangangokuthi ukugeleza kwegazi ezithweni ezibalulekile kuncipha. I-Sepsis iyisimo esiphuthumayo sezokwelapha esingaba yingozi.
Kodwa ungakhathazeki. Uma umzimba wakho unezinga eliphezulu le-cytokine futhi amasosha omzimba wakho esebenza ngokweqile, udokotela wakho angakunikeza ukwelashwa ukunciphisa lokho kuvuvukala.
Iyini iphaneli ye-cytokine?
Odokotela bangathola ukuthi umzimba wakho ukhiqiza ama-cytokine amaningi kakhulu noma ambalwa kakhulu. Lokhu bakwenza ngento ebizwa ngokuthi i-cytokine panel . Lokhu ukuhlolwa kwegazi okulula. Bathatha isampula yegazi lakho bese behlola amazinga ama-cytokine ahlobene nokuvuvukala. Uma amazinga e-cytokine ephezulu, kusho ukuthi kukhona ukuvuvukala okwandisiwe. Ngemuva kwalokho, imithi edingekayo ingaqalwa.
Izinto ezibaluleke kakhulu okudingeka sizikhumbule kule ndaba yilezi:
Ngakho-ke, cishe usuyaqonda manje ukuthi ama-cytokine abaluleke kangakanani ohlelweni lokuzivikela olunempilo emzimbeni wethu. Njenganoma yini, ukulinganisela kubalulekile.
Uma i-cytokine signaling isesilinganisweni esifanele nangendlela efanele, ingasivikela ekuthelelekeni. Kodwa-ke, uma amazinga e-cytokine eba phezulu kakhulu, ukuvuvukala okweqile okubangelwa yilokhu kungaba yingozi uma kungelashwa.
Ngakho-ke, kubaluleke kakhulu ukuqaphela lokhu kuxhumana okumangalisayo okwenzeka emizimbeni yethu. Uma unemibuzo noma ukungabaza ngalokhu, ungalokothi unqikaze ukukhuluma nodokotela.

Ayini ngempela ama-cytokine?
Kalula nje, ama-cytokine awuhlobo lweprotheni. Afana nezithunywa zamakhemikhali ezidlulisela ulwazi ohlelweni lwethu lokuzivikela komzimba . Cabanga ngohlelo lwethu lokuzivikela komzimba njengebutho elivikela izwe. Leli butho linamagatsha ahlukene, amasosha. Ngubani othumela la masosha (okungukuthi amasosha omzimba) imiyalezo efana nokuthi, "Nansi isitha!" "Hamba lapha ulwe!" "Zivikele kanje!"? Yilokho okwenziwa yilawa ma-cytokine . Lapho amagciwane anjengegciwane, amagciwane, amabhaktheriya, noma izinto ezibangela ukungezwani komzimba zingena emizimbeni yethu, lawa ma-cytokine atshela amangqamuzana ethu omzimba ukuthi "aqale ukusebenza, alwe nalaba bahlaseli." Akukhona lokho kuphela, kodwa lawa ma-cytokine asiza ukugcina uhlelo lwethu lokuzivikela komzimba lusebenza kahle futhi luhambisana, ngisho noma kungekho songo emizimbeni yethu. Njengoba nje imiyalezo ishintshaniswa ukuze ihhovisi lethu liqhubeke kahle.
Yiziphi izinhlobo zama-cytokine ezikhona?
Kunezinhlobo eziningi ezahlukene zamalungu alo mndeni wezithunywa ezibizwa ngokuthi ama-cytokine. Zonke zitshela amangqamuzana omzimba ukuthi aye kuphi nokuthi enzeni. Kodwa kunezinhlobo eziningana, kuye ngemisebenzi yazo ethile. Ake sibheke ezimbalwa zezinhlobo eziyinhloko.
Ama-Chemokine: Lawa “ama-guider.” Afana ne-GPS. Yiwo aqondisa amangqamuzana omzimba endaweni yokutheleleka, ewatshela ukuthi, “Wozani ngapha.”
Ama-Interferons: Igama lawo lisho ukuthi “ukuphazamisa.” Kusho ukuthini ukuphazamisa? Asebenza ngokuvimbela amagciwane ukuthi angangeni emaseli ethu futhi enze amagciwane engeziwe ('ukuziphindaphinda'). Kufana nokubeka uphawu lwamagciwane oluthi, “Akusekho ukuya lapha!”
Ama-Interleukin: Leli gama lisuselwa emagameni athi "inter" (phakathi) kanye nelithi "leukocyte" (iseli elimhlophe legazi). Ngaphambilini kwakucatshangwa ukuthi la makhemikhali axhumana kuphela phakathi kwamangqamuzana amhlophe egazi. Kodwa-ke, manje sekutholakale ukuthi akhiqizwa nangamanye amangqamuzana nokuthi axhumana naphakathi kwamangqamuzana angewona amhlophe egazi.
I-Tumor Necrosis Factor (TNF): Lokhu kuzwakala njengegama elibi, akunjalo? Umsebenzi walo oyinhloko ukwenzaIlawula ukuvuvukala , okusho ukuvuvukala nokubomvu. Iphinde inikeze amaseli omzimba amandla okubhubhisa amaseli esimila .
Izinto Ezivuselela Ikholoni (CSF): Lezi zifana "nabaphathi befektri yamaseli" emzimbeni wethu. Ngoba, kukhona uhlobo olukhethekile lweseli olubizwa ngokuthi amaseli egazi aqinile (HSC) . Lawa maseli angenza zonke izinhlobo zamaseli egazi njengeeseli ezimhlophe zegazi, amaseli abomvu egazi, nama-platelet. Le "nqubo yokukhiqiza" ( i-Hematopoiesis ) isizwa yile "CSF", okungukuthi, itshela amaseli egazi ukuthi "akhiqize lolu hlobo lweseli". Isibonelo, " i-G-CSF " isiza ekwenzeni uhlobo lweseli elimhlophe legazi elibizwa ngokuthi "i-Neutrophil" . Lawa ma-neutrophil abaluleke kakhulu ekulweni nokutheleleka.
Amanye ama-cytokine aqanjwe ngohlobo lweseli eliwakhiqizayo.
Ama-lymphokine: Ngoba akhiqizwa uhlobo lweseli elimhlophe legazi elibizwa ngokuthi ama-lymphocyte.
Ama-monokine: Ngoba akhiqizwa uhlobo lweseli elimhlophe legazi elibizwa ngokuthi ama-monocyte.
Yiluphi usizo olunikezwa ama-cytokine emizimbeni yethu?
Uma sikhuluma ngama-cytokine, abantu abaningi bacabanga ngokuvuvukala . Uma sicabanga ngokuvuvukala, sicabanga ngokuvuvukala okucasulayo kanye nokubomvu okwenzeka ngesikhathi sokugula noma ukungezwani komzimba. Kodwa ukuvuvukala empeleni kuwuphawu lokuthi amangqamuzana omzimba wethu alwa nabahlaseli noma aphulukisa izicubu ezilimele.
Cabanga nje uma usika umunwe wakho, indawo iyavuvukala futhi ibe bomvu, akunjalo? Lokho ukuvuvukala. Lokho kusho ukuthi ama-cytokine athunyelwa lapho, athi, "Kunenkinga lapha, woza uzobheka, bese upholisa inxeba," bese kulethwa amangqamuzana afanele aqale ukusebenza.
Ngakho-ke, ama-cytokine afana nezithunywa zamakhemikhali ezitshela amangqamuzana ukuthi "aziphatha kanjani." Ngokuyinhloko abonisa izinto ezifana nalezi:
Ukusebenza kweseli: Kutshela amaseli ukuthi aye kuphi nokuthi enzeni. Isibonelo, kuqondisa amaseli omzimba endaweni yokutheleleka ukuze alwe namagciwane lapho. Kuphinde kubonise ukwandisa noma ukunciphisa izinqubo ezihlobene nokuvuvukala.
Ukwehlukaniswa kwamaseli:Lokhu kufana nesikole sokuqeqesha. Bathatha amangqamuzana angakavuthwa bese bewaqeqesha ukuba abe “lolu uhlobo lweseli ofuna ukuba yilo uma ukhula.” Isibonelo, bathatha iseli elincane bese beliguqula libe iseli legazi elimhlophe elingalwa nokutheleleka.
Ukwanda kwamaseli: Lokhu kusho "ukwenza abantu abaningi bafane nawe." Kufana nokwenza ikhophi. Isibonelo, uma udinga amaseli egazi amhlophe engeziwe ukuze ulwe nokutheleleka, utshela amaseli akho amhlophe egazi akhona ukuthi "wenze abantu abaningi bafane nawe."
Akukhona lokho kuphela, kodwa ngezinye izikhathi ama-cytokine aphinde atshele amangqamuzana omzimba wethu ukuthi "akhiqize ama-cytokine engeziwe." Bese impendulo yokuvuvukala iyanda kakhulu.
Uyini umehluko phakathi kwama-cytokine akhuthaza ukuvuvukala kanye nama-cytokine alwa nokuvuvukala?
Uma amasosha ethu omzimba esebenza kahle, ama-cytokine abangela ukuvuvukala uma kudingeka ukuze alwe nabahlaseli futhi aphulukise izicubu. Bese bethi, "Kulungile, sekwanele, sekwanele," bese benciphisa futhi bamise ukuvuvukala. Kufana ne-accelerator (i-gas pedal) kanye ne-brake emotweni.
Ama-cytokine akhuthaza ukuvuvukala: Lawa “ama-gas pedals.” Laba ngabantu abakhombisa ukuthi ukuvuvukala kuqala futhi kwanda. Lapho isitha singena emizimbeni yethu, bathi, “Wonke umuntu, lungiselelani impi!”
Ama-cytokine alwa nokuvuvukala: Lawa "amabhuleki". Lawa yiwo abonisa ukuthi kufanele kumiswe futhi kuncishiswe ukuvuvukala . Ngoba, uma ukuvuvukala kwanda kakhulu, kungalimaza nezicubu ezinhle emzimbeni wethu. Lawa yiwo avimbela lokho.
Uma sikhuluma iqiniso, ukuyeka ukuvuvukala kubaluleke kakhulu njengokukuqala. Ukuvuvukala kakhulu kungaholela ezimpawini ezingakhululekile, ezifweni zesikhathi eside, futhi ngezinye izikhathi, uma kungelashwa, kungaba yingozi empilweni.
Lawa ma-cytokine asebenza kanjani?
Lokhu kwenzeka ngendlela elula kakhulu. Cabanga nge-cytokine njengesihluthulelo , futhi kukhona i-'receptor' esiseleni ehambisana naleyo khiye. Lapho i-cytokine (isihluthulelo) ihamba futhi ingena kuleyo 'receptor' ekuleyo seli, leyo seli ithola umlayezo othi "Yini okufanele uyenze?". Bese lelo seli lisebenza ngokwalowo myalezo. Ake sibheke isibonelo. Uma elinye lamaseli ethu omzimba libona into eyingozi, njengegciwane, ngaphakathi emzimbeni, lelo seli likhipha i-cytokine. Le cytokine ihamba ngegazi noma ngezicubu bese ithola iseli eline-'receptor' elihambisana nayo. Lapho i-cytokine ibopha kuleyo 'receptor', iseli elamukela lowo myalezo lithola umlayezo. Mhlawumbe lelo seli lizoya lapho igciwane likhona bese liqala ukulihlasela. Noma, lizoqinisa ukuzivikela kwalo ukuvimbela igciwane ukuthi lingangeni. Ama-Cytokine angathumela imiyalezo esiseleni esiwakhiphe, kumaseli aseduze, noma ngisho nasemaseli akude.
Ukuthumela imiyalezo kuseli yayo (`i-Autocrine signaling`):I-cytokine ibopha ku-receptor esesiseleni esiyikhiphile.
I-Paracrine signaling: ibopha kuma-receptor kumaseli aseduze.
Ukubonakaliswa kwe-Endocrine: Ama-Cytokine abopha kuma-receptor kumaseli akude kakhulu neseli eliwakhiphe.
Kukhona amangqamuzana kuyo yonke imizimba yethu anama-cytokine `receptors. Eqinisweni, izitho eziningi emizimbeni yethu ziqukethe amangqamuzana anala ma-`receptors.' Yingakho ukuvuvukala kungenzeka noma kuphi.
Avelaphi ama-cytokine? Ubani owawenzayo?
Ama-cytokine avame kakhulu emzimbeni wethu akhiqizwa amangqamuzana omzimba , okungamaseli amhlophe egazi (ama-leukocyte). Amanye alawa ahlanganisa:
Ama-Macrophage
Amaseli e-dendritic
Ama-lymphocyte (ama-lymphocyte e-T ne-B)
Ama-monocyte
Ama-neutrophil
Ama-Basophil
Ama-Eosinophil
Amaseli e-mast
Kodwa akuwona amangqamuzana omzimba kuphela, kodwa nezinye izinhlobo eziningi zamangqamuzana emzimbeni wethu zingakhiqiza ama-cytokine. Nazi izibonelo ezimbalwa:
Amaseli e-Endothelial: Amaseli angaphakathi kwemithambo yegazi yethu.
Amaseli e-Epithelial: Amaseli ahambisana nezitho zethu.
Ama-Fibroblast: Amaseli atholakala ezicutshini ezixhumeneyo.
Amaseli e-Stromal: Olunye uhlobo lweseli olutholakala ezicutshini ezixhumeneyo.
Amaseli eSchwann: Amaseli azungeze amaseli ezinzwa (ama-neurons).
Uhlobo olufanayo lwe-cytokine lungakhiqizwa izinhlobo ezahlukene zamaseli.
Yiziphi izifo ezingahlotshaniswa nama-cytokine?
Ama-Cytokine abalulekile ohlelweni lwethu lokuzivikela komzimba, futhi ahlotshaniswa nezifo eziningi esingazithola. Ngokuvamile, ama-cytokine asiza ekusigcineni singenazo izifo. Kodwa-ke, ngezinye izikhathi uhlelo lwethu lokuzivikela komzimba lungakhiqiza ama-cytokine amaningi kakhulu. Lokhu kungaba ukuphendula ekuthelelekeni noma njengengxenye yokwelashwa okufana ne-immunotherapy . Lokhu kubizwa ngokuthi i-cytokine release syndrome (CRS) noma i-cytokine storm . Lokhu kungabangela izimpawu ezahlukahlukene ezithinta izinhlelo eziningi zomzimba wethu. Uma kungelashwa, lesi simo singasongela impilo. Uma kunama-cytokine amaningi kakhulu, impendulo yokuvuvukala iyanda. Lokhu kuvuvukala okweqile kungalimaza izicubu, okuholela ezifweni ezifana nalezi:
Izifo ezizenzakalelayo: Yilapho amasosha ethu omzimba ehlasela ngephutha amangqamuzana ethu aphilile.
Izinkinga ze-Metabolic:Izinkinga ezihlobene nokuguqulwa kwe-metabolism, inqubo imizimba yethu eguqula ngayo ukudla kube amandla futhi isuse imfucuza.
Umdlavuza
I-Sepsis: Lokhu kwenzeka lapho impendulo yomzimba yokuvuvukala iba nzima kangangokuthi ukugeleza kwegazi ezithweni ezibalulekile kuncipha. I-Sepsis iyisimo esiphuthumayo sezokwelapha esingaba yingozi.
Kodwa ungakhathazeki. Uma umzimba wakho unezinga eliphezulu le-cytokine futhi amasosha omzimba wakho esebenza ngokweqile, udokotela wakho angakunikeza ukwelashwa ukunciphisa lokho kuvuvukala.
Iyini iphaneli ye-cytokine?
Odokotela bangathola ukuthi umzimba wakho ukhiqiza ama-cytokine amaningi kakhulu noma ambalwa kakhulu. Lokhu bakwenza ngento ebizwa ngokuthi i-cytokine panel . Lokhu ukuhlolwa kwegazi okulula. Bathatha isampula yegazi lakho bese behlola amazinga ama-cytokine ahlobene nokuvuvukala. Uma amazinga e-cytokine ephezulu, kusho ukuthi kukhona ukuvuvukala okwandisiwe. Ngemuva kwalokho, imithi edingekayo ingaqalwa.
Izinto ezibaluleke kakhulu okudingeka sizikhumbule kule ndaba yilezi:
Ngakho-ke, cishe usuyaqonda manje ukuthi ama-cytokine abaluleke kangakanani ohlelweni lokuzivikela olunempilo emzimbeni wethu. Njenganoma yini, ukulinganisela kubalulekile.
Uma i-cytokine signaling isesilinganisweni esifanele nangendlela efanele, ingasivikela ekuthelelekeni. Kodwa-ke, uma amazinga e-cytokine eba phezulu kakhulu, ukuvuvukala okweqile okubangelwa yilokhu kungaba yingozi uma kungelashwa.
Ngakho-ke, kubaluleke kakhulu ukuqaphela lokhu kuxhumana okumangalisayo okwenzeka emizimbeni yethu. Uma unemibuzo noma ukungabaza ngalokhu, ungalokothi unqikaze ukukhuluma nodokotela.
