Reka twige gusa ibyerekeye Apoptosis: uburyo butangaje uturemangingo tw’umubiri wacu 'dupfa nkana'!

Umubiri wacu ni imashini itangaje cyane, si byo se? Hari byinshi biba muri twe tutazi. Hari igihe, uturemangingo twacu duhabwa ikimenyetso kigira kiti "Sawa, igihe cyawe kirarangiye," maze tugashyirwa mu buryo bunoze cyane, nta kintu na kimwe cyangiza hafi yatwo. Ibyo ni byo twita apoptosis mu buvuzi. Ni nk'ubwiyahuzi bwateguwe, ariko bibaho ku bw'inyungu zacu bwite.

Apoptosis ni iki mu by'ukuri?

Mu magambo make, apoptosis ni inzira yitwa 'gupfa kw'uturemangingo' umubiri wacu ukoresha mu gukuraho uturemangingo twangiritse, dushaje, cyangwa tutagikenewe. Ijambo 'gushyirwa mu bikorwa' ni ingenzi hano. Bisobanura ko umubiri wacu uzi ko utwo turemangingo tugomba gupfa, kandi umubiri uyobora iyi nzira kuva mu ntangiriro kugeza ku iherezo.

Aho kwigabanya no gukura nk'uturemangingo tuzima, uturemangingo twibasiwe n'imisemburo turasenyuka mu buryo bunoze hanyuma tugapfa.

Tekereza ko amakuru y’uturemangingo mu turemangingo, ni ukuvuga ADN, yangiritse. Iyo ako karemangingo gakomeje kwigabanyamo ibice, uturemangingo dushya tuzatangira kwirema no kwirundanya mu mubiri hamwe n’iyo ADN yangiritse. Iyi ni yo mpamvu ikomeye itera indwara zikomeye nka kanseri . Imwe mu nshingano z’ingenzi za apoptosis ni ukurinda ko ibintu nk’ibyo bibaho.

Iyo iki gikorwa kibaye nk'uko byari biteganyijwe, tubyungukiramo. Ariko iyo hari ikintu kitagenze neza muri ubu buryo, apoptosis ishobora kubaho cyane cyangwa ntibe ihagije. Byombi bishobora kutugiraho ingaruka mbi.

Kuki ibi ari ingenzi cyane ku mubiri wacu?

Apoptosis ni inzira irinda ubuzima bwacu ikuraho uturemangingo tutagikenewe mu mibiri yacu. Iyi nzira itangira mbere yuko tuvuka.

• Imikurire y'uruhinja: Tekereza ukuntu ikiganza cy'umwana mu nda cyabanje kumera nk'urugingo rumwe. Hanyuma, mu gihe gikwiye, uturemangingo turi hagati y'intoki dupfa binyuze mu nzira yitwa apoptosis. Ni bwo intoki eshanu zitandukana neza.
• Gusimbuza ingirabuzimafatizo zishaje izindi nshya: Ingirabuzimafatizo n'ingingo mu mubiri wacu bihora byivugurura. Iyi gahunda ikuraho ingirabuzimafatizo zishaje.
• Gufasha ubudahangarwa bw'umubiri: Ibi bifasha ubudahangarwa bwacu kurwanya indwara.
• Kugira ngo ukureho uturemangingo twangiritse:Uturemangingo twangiritse ku buryo bukabije turakurwa mu mubiri.
• Kurinda igabanyuka ry'uturemangingo twangiritse: Ibi nibyo bigenzura iterambere ry'ibintu nka kanseri.
• Kugira ngo umubiri ukomeze kugira ubuzima bwiza: Ibi ni ingenzi kugira ngo ingingo z'umubiri zikomeze kuba nziza.

Iyi gahunda igenda ite?

Poroteyine zimwe na zimwe mu mibiri yacu zitangira iyi nzira yo kubura umwuka. Urugero rwiza rw'ibi ni poroteyine yitwa p53 . Nanone yitwa 'poroteyine igabanya ikibyimba' kuko irinda igabanyuka ry'uturemangingo ritagenzurwa (rishobora gutera ibibyimba).

Mu magambo make, p53 ni nk''umurinzi' uri mu turemangingo twacu. Iyi poroteyine ihora igenzura ADN y'uturemangingo kugira ngo irebe niba hari ibyangiritse. Iyo ibyangiritse ari bike, itanga amabwiriza yo kubisana. Ariko iyo ibyangiritse ari byinshi cyane ku buryo bitabasha gusanwa, poroteyine ya p53 ihagarika ingirabuzimafatizo kwigabanyamo ibice. Ahubwo, imenyesha ingirabuzimafatizo gutangira apoptosis.

Iyo apoptosis itangiye, hatangira impinduka nyinshi za shimi zicamo uturemangingo mo ibice bito. Hanyuma, aka karemangingo kari gupfa kohereza ikimenyetso ku 'turemangingo dusukura' twitwa phagocytes (ubwoko bw'uturemangingo tw'amaraso twera) ngo "tuze turye utwo duce." Iki ni ikintu cyiza cyane gukora. Ni nko gupakira imyanda ukayiha ikamyo itwara imyanda. Ibi bivuze ko uturemangingo tuyikikije tudakomereka, nta bubyimba buhari.

Bigenda bite iyo habayeho apoptosis nyinshi cyangwa nkeya cyane?

Kimwe n'ibindi byose, iyi gahunda igomba kuringanizwa. Kurenza urugero ni ikibazo, guke cyane ni ikibazo. Reka turebe uko bigenda.

Ni irihe tandukaniro riri hagati ya Apoptosis na Necrosis?

Nubwo izi nzira zombi zituma uturemangingo dupfa, hari itandukaniro rinini hagati yabyo. Abantu benshi bavangavanga ibyo byombi.

Abashakashatsi batekerezaga ko apoptosis ari urupfu rwateguwe kandi ruteguwe, naho necrosis ikaba urupfu rutunguranye, ruteje akaduruvayo. Ku rugero runaka, ni ukuri. Muri necrosis, ingirabuzimafatizo irabyimba kandi igaturika. Hanyuma ibiri mu ngirabuzimafatizo bijugunywa hanze, bigatera ububyimbirwe mu ngingo zikikije. Ariko muri apoptosis, ibyo ntibibaho. Ingirabuzimafatizo irapfunyikwa neza kandi ikagenda nta mvururu.

Ariko, ubushakashatsi bushya bwagaragaje ko hari ubwoko bumwe na bumwe bwa necrosis, nka apoptosis, bubaho mu buryo bwateguwe. Amazina nka necroptosis na pyroptosis akoreshwa kuri ibi. Bityo rero itandukaniro riri hagati y'izi nzira zombi ntirihora risobanutse neza.

Uruhare rwa apoptosis mu kuvura indwara

Abashakashatsi bazi ko impinduka mu mikorere ya apoptosis zishobora gutera indwara zimwe na zimwe, bityo ubu barimo kugerageza gukora imiti ishobora kurwanya apoptosis.

• Ku bijyanye na kanseri: Kubera ko inzira yo kuzura kw'uturemangingo twa kanseri idakora neza, utwo turemangingo dukomeza kwigabanyamo ibice tudapfa. Ubu bushakashatsi burimo gukorwa ku miti ishobora gutangiza cyangwa kwihutisha inzira yo kuzura kw'uturemangingo twa kanseri.
• Ku ndwara zo mu bwonko: Mu ndwara nka Alzheimer, uturemangingo tw’ubwonko tuzima duhura n’ingaruka mbi cyane z’imisemburo. Mu bihe nk’ibi, abashakashatsi barimo kugerageza gukora imiti ibuza cyangwa igabanye imisemburo y’imisemburo.

Ubu bushakashatsi buracyakomeje. Ubu bumenyi buzaba ingenzi cyane mu kuvura indwara nyinshi mu gihe kizaza. Niba ufite ikibazo cy’uburwayi muri urwo rwego, ushobora kubaza muganga wawe ibisobanuro birambuye n’amakuru agezweho kuri cyo.
