Mibvunzo yemuenzaniso nekukurukurirana: Mhinduro yeMadziviriro eMuviri uye Kuzivikanwa kweMuviri
Sisitimu yekudzivirira muviri inzvimbo yakaoma yenhengo, masero, uye mamorekuru mumuviri anoshanda pamwe chete kuti atidzivirire kubva kuzvirwere nehutachiona. Kunzwisisa mhinduro yemuviri uye kuti muviri unoziva sei zvinhu zvekunze kwakakosha mubiology nekurapa. Muchinyorwa chino, tichakurukura mimwe mienzaniso yezvinetso zvine chekuita nemhinduro yemuviri uye kuzivikanwa kwemuviri, pamwe nekukurukurirana kwakadzama kuti tibatsire kusimbisa kunzwisisa kwedu nyaya iyi.
Mubvunzo 1: Tsanangura Musiyano Uripo Pakati Pekusadzivirira Kuzvarwa Nekugadziriswa
Kukurukurirana:
Kusadzivirira muviri kubva muzvirwere zvemuviri (innatured immunity) uye kusadzivirira muviri kunokonzerwa nehutachiona (adaptive immunity) ndizvo zvinhu zviviri zvikuru zvemuviri zvinoshanda pamwe chete kudzivirira muviri kubva kuzvirwere zvinotapukira.
- Kusadzivirirwa Kwemuviri:
– Kukurumidza Kupindura: Inopindura nekukurumidza kuzvirwere, kazhinji mukati memaminitsi kana maawa.
– Hazvina kutsanangurwa: Hazvisiyanisi mhando dzezvirwere; zvinoshanda senzira yekutanga yekudzivirira.
– Zvikamu zvikuru: Zvipingamupinyi zvemuviri (ganda nemukati), masero e-phagocytic (akadai semacrophages nema neutrophils), masero ekuuraya echisikigo, uye mapuroteni eplasma (akadai se complement).
– Ndangariro: Haina ndangariro yemuviri inochengetedza muviri, saka mhinduro yacho yakafanana nekubatwa nehutachiona kwega kwega.
- Kusagadzikana Kunochinjika:
– Kupindura Zvishoma: Zvinotora nguva yakareba kuti zvishande (mazuva kusvika mavhiki) kana hutachiona hwatanga.
– Zvakanyanya: Mhinduro chaiyo kune chimwe chirwere.
– Zvikamu Zvikuru: B neT lymphocytes, pamwe chete nema antibodies anogadzirwa neB cells.
– Ndangariro: Kuva nepfungwa yekudzivirira muviri, saka inogona kupa mhinduro inokurumidza uye yakasimba kana munhu akasangana nechirwere chimwe chete ichocho.
Mhando mbiri idzi dzedziviriro dzinobatsirana. Dziviriro yemuviri inokupa dziviriro yekutanga nekukurumidza, nepo dziviriro inochinjika ichipa dziviriro yenguva refu uye chaiyo.
Mubvunzo 2: Chii chinonzi T-Regulatory Cells uye Basa Rawo Nderipi Mumhinduro Yemuviri?
Kukurukurirana:
Masero eT-regulatory cells (Tregs) iboka diki remasero eT anoita basa rakakosha mukuchengetedza homeostasis yemuviri uye kudzivirira autoimmune immunity. Anobatsira mu:
– Inodzora Kupindura Kwemuviri: Masero eTregs anodzora uye anodzora mhinduro dzakawandisa dzemuviri dzinogona kukonzera kukuvara kwenyama yemuviri.
– Kuchengetedza Kushivirira Kwemuviri Wemuviri: Kudzivirira masoja emuviri kuti asarwisa masero nematishu emuviri (autoimmune). Izvi zvinoitwa nekudzora mashandiro emasero eT anobatsira anosangana nemaantigen emuviri.
– Dzivirira Kuzvimba: Masero eTregs anoderedza kuzvimba nekugadzira ma cytokines anodzivirira kuzvimba akadai seIL-10 neTGF-beta.
Nekudzora mhinduro yekudzivirira muviri, Tregs inochengetedza chiyero pakati pekubvisa chepfu kubva kune dzimwe nyika uye kudzivirira kwematishu emuviri.
Mubvunzo 3: Tsanangura Maitiro Ekuita Kwemasoja Emuviri Mukurwisa Utachiona
Kukurukurirana:
Ma antibodies mapuroteni anogadzirwa nemasero eB, anotenderera muropa, uye anoita basa rakakosha muhumoral immune system. Ma antibodies anoziva maantigen chaiwo pamusoro pehutachiona uye anoita kuti nzira dzinotevera dzirwise hutachiona:
– Kusapindirana kwemasero: Masoja ekudzivirira chirwere anogona kudzikamisa hutachiona nekunamatira kuzvikamu zvinoshandiswa nehutachiona kuti zvipinde mumasero emuviri, semuenzaniso kufukidza hutachiona.
– Opsonization: Masoja ekudzivirira chirwere anobatanidzwa pamusoro pezvirwere anobatsira pakuita kuti pave ne phagocytosis. Masero e phagocytic, akadai se macrophages nema neutrophils, ane ma receptors echikamu cheFc chema antibodies, zvichiita kuti zvive nyore kuziva nekudya zvipembenene.
– Kushanda Kwekuwedzera: Masoja emuviri anogona kukonzera kuwanda kwemasero emuviri zvichikonzera kuparadzwa kwemasero kana kuwedzera kwemhinduro yemuviri kuburikidza nemaitiro akadai se opsonization uye chemotaxis.
– Kuungana uye Kudonha kwemvura: Masoja ekudzivirira chirwere anogona kuunganidza utachiona hunonyungudika kana maantigen kuitira kuti zvive nyore kuziva nekubvisa nemasoja emuviri.
Kirasi yega yega yemasoja ekudzivirira chirwere (IgM, IgG, IgA, IgE, uye IgD) ine basa rayo uye nzvimbo yayo mumuviri, zvichibatsira kukurudzira mhinduro yekudzivirira chirwere inonangwa uye inoshanda.
Mubvunzo 4: Muviri unosiyanisa sei masero emuviri neasiri iwo emuviri?
Kukurukurirana:
Kugona kwemuviri kusiyanisa masero emuviri neasiri emuviri ndiwo hwaro hwemhinduro yemuviri pakudzivirira hutachiona hwemuviri uye kudzivirira autoimmune. Maitiro aya anotungamirirwa nemamorekuru anonzi Major Histocompatibility Complex (MHC):
– MHC Kirasi I: Inowanikwa pamasero ese emuviri kunze kwemasero matsvuku eropa. Inopa maantigen kubva mukati mesero kuti masero eT ane chepfu aanogona kuongorora. Kana akaonekwa ari ega, hapana chimwe chiitiko chinoitika.
– MHC Kirasi II: Inowanikwa chete pamasero anogadzira maantigen (APCs) akadai semacrophages, masero edendritic, uye masero eB. Inopa maantigen ekunze kumasero eT anobatsira, ayo anobatsira kumutsa masero eB necytotoxic.
Masoja ekudzivirira muviri anopinda mugwara rethymus nebone morrow kuti akwanise kushivirira maantigens emuviri. Masero anowanzo bviswa panguva iyi kudzivirira kukura kwe autoimmune immune system.
Mhedziso
Kunzwisisa masoja emuviri uye kuti muviri unoona sei uye unopindura sei kuzvirwere ndizvo zvakakosha mubiology uye mushonga. Chinyorwa chino chinopfupisa pfungwa dzinoverengeka dzakakosha, kusanganisira mutsauko uripo pakati pemasoja emuviri neanochinjika, basa remasero eTreg, mashandiro emasoja emuviri, uye maitiro emasoja emuviri ekuzvizivisa ega uye ekusazviziva ega. Kunzwisisa kwakadzama kwenyaya idzi kunogona kugadzira nzira yekuvandudzwa kwemishonga mitsva uye hutano hwevanhu huri nani.
