Tikadwala malungo kapena chimfine, chimachepa pakatha masiku ochepa, sichoncho? Kodi munayamba mwadzifunsapo kuti zimenezo zimachitika bwanji? Tilinso ndi gulu lankhondo lalikulu mkati mwa matupi athu, lomwe limalimbana ndi majeremusi oyambitsa matenda ochokera kunja. Mmodzi mwa asilikali apadera kwambiri mu gulu lankhondo limenelo amatchedwa 'antibodies'. Lero tikambirana za mtundu wapadera wa antibody, 'Polyclonal Antibodies'. Ngakhale dzinali likumveka ngati lasayansi pang'ono, nkhaniyi ndi yosavuta. Tiyeni tiwone tsatanetsatane wa zoteteza thupi izi.
Mwachidule, kodi ma antibodies a polyclonal awa ndi chiyani?
Ma antibodies a polyclonal ndi mapuloteni ang'onoang'ono omwe ndi gawo la chitetezo chathu chamthupi. Makamaka, amapangidwa ndi gulu la maselo otchedwa plasma B cells.
Tsopano tiyeni tichepetse pang'ono izi. Tangoganizani kuti mdani wabwera m'dziko lanu. Kuti mudziwe mdaniyo, pali 'zizindikiro' zapadera pathupi lake. Zili chimodzimodzi pamene kachilombo, kachilombo kapena bakiteriya, kalowa m'thupi mwathu. Kachiromboko kali ndi 'zizindikiro' zapadera pamwamba pake. Mu zamankhwala, timatcha chizindikiro ichi kuti 'antigen' .
Chitetezo chathu cha mthupi chikawona antigen iyi, chimaizindikira ndi kunena kuti, "O... uyu si m'modzi mwa ife, ndi munthu wochokera kunja." Kenako gulu lathu lankhondo, lomwe ndi ma antibodies, limayamba kugwira ntchito.
Koma pali chinthu china chaching'ono apa. Pa antigen imodzi, ndiko kuti, pa thupi la mdani mmodzi, pali malo angapo omwe ma antibodies athu amatha kugwirapo. Monga momwe zilili ndi mabowo angapo kuti makiyi alowe pakhomo limodzi. Timatcha mabowo onsewa kuti 'epitope' .
Mawu oti 'polyclonal' amatanthauza 'kuchokera ku mitundu yosiyanasiyana'. Chifukwa chake, ma antibodies a polyclonal ndi gulu la mitundu yosiyanasiyana ya ma antibodies omwe amatha kuukira malo osiyanasiyana (epitopes) pa mdani yemweyo (antigen). Izi zimachepetsa kwambiri mwayi wa mdani wopulumuka.
Ngakhale kuti izi zimapangidwa mwachilengedwe m'thupi lathu, kuti zigwiritsidwe ntchito ngati mankhwala nthawi zina zimachotsedwa m'matupi a nyama monga akalulu ndi nkhosa, kapena m'magazi a anthu omwe achira matenda enaake.
Kodi izi zimagwira ntchito bwanji mkati mwa thupi?
Njira yochitira izi ndi yosangalatsa kwambiri. Taganizirani ngati kiyi ndi kamba.
1. Mdani amalowa: Kachilombo kapena mabakiteriya amalowa m'thupi mwathu. Ali ndi 'pigment' pamwamba pake. Awa ndi ma antigen.
2. Tsatanetsatane wa fulu: Koma fulu lililonse lili ndi mabowo angapo a makiyi. Izi ndi ma epitopes.
3. Gulu lankhondo la makiyi lafika: Chitetezo chathu cha mthupi chikangoona kachilomboka, chimapanga 'mitundu yosiyanasiyana ya makiyi' omwe amalowa m'bowo lililonse. Gulu lankhondo la makiyi amenewo limatchedwa ma polyclonal antibodies.
4. Nkhondo ikuyamba:Mitundu yosiyanasiyana ya makiyi (ma antibodies) amamangirira ku mabowo osiyanasiyana (epitopes) m'thupi la mdani. Amaukira mdani yemweyo kuchokera m'malo osiyanasiyana.
5. Amawononga mdani: Ma antibodies akamamatira motere, maselo ena m'thupi amatha kuzindikira mosavuta ndikuwononga mdani uyu.
Mwachidule, luso la ma antibodies a polyclonal ndilakuti m'malo moukira mdani m'njira imodzi yokha, amamuukira kuchokera mbali zosiyanasiyana komanso m'njira zosiyanasiyana. Izi zimapangitsa kuti chitetezo cha mthupi chikhale champhamvu komanso chogwira ntchito bwino .
Kodi izi zimagwiritsidwa ntchito chiyani mu zamankhwala?
Kuwonjezera pa kupangidwa mwachibadwa m'matupi athu, ma antibodies amenewa amagwiritsidwa ntchito pa ntchito zambiri zofunika pa zamankhwala.
- Kuzindikira Matenda: Mayeso ena a labotale, monga ELISA ndi immunohistochemistry, amagwiritsidwa ntchito kuzindikira kupezeka kwa matenda kapena khansa.
- Pa kafukufuku wa sayansi: Ofufuza amagwiritsa ntchito izi kuti amvetse momwe matupi athu amagwirira ntchito komanso momwe matenda amakulira.
- Pochiza ndi kupewa matenda: Ma antibodies a polyclonal amagwiritsidwa ntchito pochiza matenda monga kumwa mankhwala mopitirira muyeso, kulumidwa ndi njoka, ndi matenda ena a magazi.
| Njira yochizira | Kufotokozera kosavuta |
|---|---|
| Mankhwala oletsa njoka (Antivenom) | Izi zili ndi ma antibodies omwe adapangidwa kuti athane ndi poizoni yemwe amalowa m'thupi njoka ikaluma. |
| Plasma Yotsitsimula | Madzi a m'magazi a munthu amene wachira matenda opatsirana amakhala ndi ma antibodies a polyclonal omwe apangidwa motsutsana ndi matendawa. Madzi a m'magazi amenewa amaperekedwa kwa wodwala kuti alandire chithandizo. |
| Digoxin immune fabric | Jakisoni woperekedwa ngati munthu wamwa mankhwala a mtima mopitirira muyeso Digoxin. |
| Rho(D) immune globulin | Katemerayu amaperekedwa kwa mayi wapakati yemwe ali ndi mtundu wa magazi wopanda Rh kuti apewe mavuto (rhesus isoimmunization) omwe angachitike ngati mtundu wa magazi a mwana utakhala ndi Rh-positive. Amaperekedwanso ngati chithandizo cha matenda a magazi otchedwa ITP (immunothrombocytopenia). |
Kodi kusiyana pakati pa ma antibodies a polyclonal ndi monoclonal ndi kotani?
Mwina munamvapo za 'ma antibodies a monoclonal.' Ngakhale kuti ma antigen onsewa amaukira, pali kusiyana kochepa koma kofunikira.
| Khalidwe | Ma antibodies a polyclonal (Polyclonal) | Ma antibodies a monoclonal (Monoclonal) |
|---|---|---|
| Momwe imapangidwira | Imapangidwa kuchokera ku gulu la mitundu yosiyanasiyana ya maselo a B. | Amapangidwa mu labotale kuchokera ku makope (ma clones) a selo limodzi la B. |
| Cholinga | Amaukira ma epitopes osiyanasiyana (madontho) pa antigen yomweyo. | Imangoukira epitope imodzi yeniyeni pa antigen imodzi yokha. |
| Kupanga | Imapezeka mwachilengedwe kuchokera ku magazi a nyama kapena anthu. | Imatengedwa m'magazi a nyama ndipo imapangidwa kukhala mabiliyoni ambiri m'labu. |
| Chilengedwe | Kusakaniza kwa ma antibodies osiyanasiyana. Ubwino wake ungasiyane malinga ndi gulu lililonse. | Popeza onse ndi mtundu umodzi wa ma antibodies, ndi okhazikika kwambiri ndipo makhalidwe awo sasintha. |
Kodi ubwino wa izi ndi wotani?
- Mtengo wotsika wopanga: Izi n'zosavuta kupanga kuposa ma antibodies a monoclonal, omwe amapangidwa movuta mu labotale.
- Kutha kuzindikira bwino: Ngakhale kuchuluka kwa antigen mu chitsanzo kuli kochepa kwambiri , kumatha kuzindikira mosavuta chifukwa kumatha kumangirira kumalo osiyanasiyana.
- Kulondola Kwambiri: Chifukwa chakuti antigen yomweyo imagwirizana ndi malo angapo, yankho lake limakhala lofanana.
Kodi palibe vuto lililonse ndiye?
Inde, palinso zovuta.
- Kusiyana kwa Ubwino: Popeza izi zimachitika mwachibadwa, pakhoza kukhala kusiyana kwa ubwino pakati pa gulu limodzi la ma antibodies ndi lina. Chifukwa chake, mphamvu zimatha kusiyana.
- Kuthekera kwa zotsatira zabodza: Nthawi zina, pamakhala kuthekera kwa kuyanjananso ndi antigen ina yofanana ndi antigen yomwe ikufunidwa. Chifukwa chake, zotsatira zabodza zitha kuchitika m'mayeso.
- Matenda a ziwengo: Pamene ma antibodies a polyclonal ochokera ku nyama agwiritsidwa ntchito pochiza anthu, pamakhala chiopsezo cha matenda a ziwengo kapena zotsatira zina zoyipa.
Kotero, monga mukuonera, ma antibodies a polyclonal awa ndi gawo lofunika kwambiri la chitetezo cha mthupi lathu, komanso mu zamankhwala. Nthawi zambiri amagwiritsidwa ntchito pofufuza ndi kuyesa matenda. Ngati muli ndi mafunso okhudza izi, makamaka ngati mukupatsidwa izi kuti mulandire chithandizo china, ndi bwino kufunsa dokotala kapena namwino wanu kuti akuthandizeni kumvetsetsa.
Uthenga Wopita Nawo Kunyumba
- Ma antibodies a polyclonal ndi gulu la chitetezo chachilengedwe chomwe chimapangidwa ndi mitundu yosiyanasiyana ya maselo m'thupi lathu.
- Izi zimagwira ntchito powukira malo osiyanasiyana (epitopes) pa mdani yemweyo (antigen) ndikuthandizira kuwononga mdaniyo. Izi zimapangitsa kuti yankho likhale lamphamvu kwambiri.
- Mu zamankhwala, amagwiritsidwa ntchito pofufuza matenda ndi matenda, komanso pochiza matenda monga njoka ndi katemera kwa amayi apakati omwe alibe Rh.
- Izi ndi zosiyana ndi ma antibodies a monoclonal, omwe amapangidwa mu labotale kuchokera ku selo imodzi ndipo amaukira cholinga chimodzi chokha.
- Ngati muli ndi nkhawa iliyonse yokhudza chithandizo chilichonse chomwe mumapatsidwa pankhaniyi, kambiranani momveka bwino ndi dokotala wanu.
