Iyo tugize umuriro cyangwa ibicurane, birakira mu minsi mike, si byo se? Wigeze wibaza uko bigenda? Dufite kandi ingabo nini mu mibiri yacu, zirwanya mikorobe zitera indwara ziturutse hanze. Umwe mu basirikare badasanzwe muri iyo ngabo yitwa 'antibodies'. Uyu munsi tugiye kuvuga ku bwoko bwihariye bwa antibodies, 'Polyclonal Antibodies'. Nubwo iri zina risa nkaho ari iry'ubumenyi, inkuru ni iyoroshye cyane. Reka turebe ibisobanuro birambuye kuri izi antibodies zo kurinda umubiri.
Mu magambo make, izi antibodies za polyclonal ni iki?
Antibodies za polyclonal ni poroteyine nto zigize ubudahangarwa bw'umubiri wacu. By'umwihariko, zikorwa n'itsinda ry'uturemangingo twitwa plasma B cells.
Noneho reka tworoshye ibi gato. Tekereza umwanzi yaje mu gihugu cyawe. Kugira ngo umenye uwo mwanzi, hari 'ibimenyetso' byihariye ku mubiri we. Ni kimwe n'iyo umugera, virusi cyangwa bagiteri, byinjiye mu mubiri wacu. Uwo mugera ufite 'ikimenyetso' cyihariye ku buso bwawo. Mu buvuzi, iki kimenyetso twita 'antigen' .
Iyo ubudahangarwa bwacu bw'umubiri bubonye iyi antigen, burayimenya bugavuga buti “Oh... uyu si umwe muri twe, ni umuntu wo hanze.” Hanyuma ingabo zacu, ni ukuvuga ubudahangarwa bw'umubiri, zitangira gukora.
Ariko hari akandi kantu gato hano. Kuri antigen imwe, ni ukuvuga ku mubiri w'umwanzi umwe, hari ahantu henshi antibodies zacu zishobora gufata. Nk'uko hari imyobo myinshi kugira ngo imfunguzo zinjire mu muryango umwe. Buri mwobo tuwita 'epitope' .
Ijambo 'polyclonal' risobanura 'kuva mu moko atandukanye'. Rero, antibodies za polyclonal ni uruhurirane rw'ubwoko bwinshi butandukanye bw'abasirikari bashobora kwibasira ahantu hatandukanye (epitopes) ku mwanzi umwe (antigen). Ibi bigabanya cyane amahirwe y'umwanzi yo kurokoka.
Nubwo ibi bikorerwa mu mibiri yacu mu buryo busanzwe, kugira ngo bikoreshwe mu buvuzi rimwe na rimwe bikurwa mu mibiri y'inyamaswa nk'inkwavu n'intama, cyangwa mu maraso y'abantu bakize indwara zimwe na zimwe.
Ibi bikora bite imbere mu mubiri?
Uburyo ibi bikorwa birashishikaje cyane. Tekereza nk'urufunguzo n'ikiyoka.
1. Umwanzi yinjira: Virusi cyangwa bagiteri byinjira mu mubiri wacu. Bifite 'ibara' ku buso bwabyo. Izi ni antigens.
2. Ibisobanuro birambuye ku nyoni: Ariko buri nyoni ifite imfunguzo nyinshi. Izi ni epitopes.
3. Ingabo z'imfunguzo zirahagera: Ubudahangarwa bwacu bw'umubiri bukimara kubona aka gakoko, bukora 'ubwoko bwinshi butandukanye bw'imfunguzo' bukwira muri buri mwobo. Ubwo bwoko bw'imfunguzo bwitwa antibodies za polyclonal.
4. Intambara iratangira:Ubwo bwoko butandukanye bw'imfunguzo (antibodies) bufata mu myobo itandukanye (epitopes) mu mubiri w'umwanzi. Butera umwanzi umwe ahantu henshi.
5. Isenya umwanzi: Iyo uturemangingo tw’umubiri dufashe dutya, izindi selile mu budahangarwa bw’umubiri zishobora kumenya no gusenya uwo mwanzi byoroshye.
Mu magambo make, umwihariko w’uturemangingo tw’umubiri twa polyclonal ni uko aho kwibasira umwanzi umwe mu buryo bumwe gusa, tumutera mu mpande zitandukanye no mu buryo butandukanye. Ibi bituma ubudahangarwa bw’umubiri bukomera kandi bukagira ingaruka nziza .
Ibi bikoreshwa mu buvuzi mu gihe ki?
Uretse kuba zikorwa mu mibiri yacu mu buryo busanzwe, izi antibodies za polyclonal zikoreshwa mu mirimo myinshi y'ingenzi mu buvuzi.
- Gusuzuma: Bimwe mu bipimo byo muri laboratwari, nka ELISA na immunohistochemistry, bikoreshwa mu gusuzuma niba hari ubwandu cyangwa kanseri.
- Ku bushakashatsi bwa siyansi: Abashakashatsi bakoresha ibi kugira ngo basobanukirwe uko imibiri yacu ikora n'uko indwara zikura.
- Kuvura no gukumira indwara: Udukoko two mu bwoko bwa polyclonal dukoreshwa mu kuvura indwara nko gukabya imiti, kurumwa n'inzoka, n'izindi ndwara zimwe na zimwe z'amaraso.
| Uburyo bwo kuvura | Ibisobanuro byoroshye |
|---|---|
| Uburozi bw'inzoka (Antivenom) | Izi zirimo uturemangingo twagenewe kurwanya uburozi bwinjira mu mubiri iyo inzoka irumye. |
| Plasma ihinduka | Plasma y'amaraso y'umuntu wakize indwara yandura irimo uturemangingo tw’umubiri twa polyclonal twakozwe turwanya iyo ndwara. Iyi plasma ihabwa umurwayi kugira ngo avurwe. |
| Digoxin immune fabric | Urushinge rutangwa mu gihe umuti w'umutima wa Digoxin urenze urugero. |
| globulin y'ubudahangarwa ya Rho(D) | Uru rukingo ruhabwa umubyeyi utwite ufite ubwoko bw'amaraso bwa Rh-negative kugira ngo hirindwe ingorane zishobora kubaho (rhesus isoimmunization) iyo ubwoko bw'amaraso y'umwana bubaye ubwa Rh-positive. Runatangwa mu kuvura indwara y'amaraso yitwa ITP (immunite thrombocytopenia). |
Ni irihe tandukaniro riri hagati y’uturemangingo tw’umubiri twitwa polyclonal na monoclonal?
Ushobora kuba warumvise ibyerekeye 'antibodies monoclonal.' Nubwo izi antigens zombi zitera, hari itandukaniro rito ariko rikomeye.
| Ibiranga | Ubudahangarwa bw'umubiri bwa polyclonal (Polyclonal) | Ubudahangarwa bw'umubiri bwa monoclonal (Monoclonal) |
|---|---|---|
| Uko byakozwe | Ikorwa mu bwoko butandukanye bw'uturemangingo twa B. | Bikorerwa muri laboratwari bivuye kuri kopi (clones) z'akaremangingo kamwe ka B. |
| Intego | Bibasira uduce dutandukanye twa epitopes (uduce) kuri antigen imwe. | Yibasira gusa epitope imwe yihariye kuri antigen imwe. |
| Umusaruro | Iboneka mu buryo busanzwe mu maraso y'inyamaswa cyangwa y'abantu. | Ikurwa mu maraso y'inyamaswa igakorwamo amamiliyari menshi muri laboratwari. |
| Kamere | Uruvange rw'uturemangingo dutandukanye. Ubwiza bushobora gutandukana bitewe n'ubwoko bw'uturemangingo. | Kubera ko zose ari ubwoko bumwe bw'uturemangingo tw'umubiri, zirahamye cyane kandi imiterere yazo ntihinduka. |
Ni izihe nyungu z'ibi?
- Igiciro gito cyo gukora: Ibi biroroshye gukora kurusha antibodies za monoclonal, zikorwa mu buryo bugoye muri laboratwari.
- Ubushobozi bwiza bwo kumenya: Nubwo ingano ya antigen mu gipimo yaba ari nto cyane , izi zishobora kuyimenya byoroshye kuko ishobora kwihambira ahantu hatandukanye.
- Uburyo bworoshye bwo kugaragaza imiterere y’umubiri: Kubera ko antigen imwe ifata ahantu henshi, igisubizo kiba gihamye kurushaho.
None se nta kibazo kirimo?
Birumvikana ko hari n'ibibi.
- Ihindagurika ry'Ubwiza: Kubera ko ibi bibaho mu buryo busanzwe, hashobora kubaho itandukaniro ry'ubwiza hagati y'itsinda rimwe ry'abashinzwe kurwanya indwara n'irindi. Kubwibyo, ubushobozi bushobora gutandukana.
- Ishobora gutanga ibisubizo by'ukuri bitari byo: Hari igihe, hari amahirwe yo guhuza antigen n'indi antigen isa na antigen. Kubwibyo, ibisubizo by'ukuri bitari byo bishobora kubaho mu bizamini.
- Ubwivumbure bw'umubiri: Iyo ubudahangarwa bw'umubiri bwa polyclonal bukomoka ku nyamaswa bukoreshejwe mu kuvura abantu, hari ibyago byo kugira ubwivumbure bw'umubiri cyangwa izindi ngaruka mbi.
Nkuko mubibona, izi antibodies za polyclonal ni ingenzi cyane mu buvuzi bw'umubiri wacu, ndetse no mu buvuzi. Zikunze gukoreshwa mu bushakashatsi no mu bipimo byo gusuzuma indwara. Niba ufite ikibazo kuri ibi, cyane cyane niba uhabwa izi antibodies kugira ngo zigufashe kuvurwa, ni byiza kubaza muganga wawe cyangwa umuforomo kugira ngo akusobanurire.
Ubutumwa bwo kujyana mu rugo
- Antibodies za polyclonal ni itsinda ry'ubwirinzi karemano bukorwa n'ubwoko butandukanye bw'uturemangingo mu budahangarwa bw'umubiri wacu.
- Ibi bikora mu gutera ahantu hatandukanye (epitopes) ku mwanzi umwe (antigen) no gufasha mu gusenya uwo mwanzi. Ibi bituma igisubizo gikomera cyane.
- Mu buvuzi, zikoreshwa mu gusuzuma no gukora ubushakashatsi, ndetse no mu kuvura nk'ubumara bw'inzoka no gukingira ababyeyi batwite badafite Rh.
- Izi zitandukanye n'uturemangingo tw’umubiri twitwa monoclonal, dukorerwa muri laboratwari duturutse ku karemangingo kamwe kandi tugatera ikintu kimwe gusa.
- Niba ufite impungenge ku bijyanye n'ubuvuzi ubwo aribwo bwose uhabwa muri urwo rwego, ganira na muganga wawe mu buryo busobanutse neza.
