▎ Thymosin Alpha-1 Nnyocha
Kedu ihe bụ Thymosin Alpha-1?
Thymosin Alpha-1 bụ polypeptide nke mejupụtara 28 amino asịd. O doro anya na ọ dị na thymus ma na-arụ ọrụ dị oke mkpa na ntozu oke na usoro dị iche iche nke mkpụrụ ndụ T.
Kedu ihe ndabere nyocha nke Thymosin Alpha-1?
Thymosin Alpha-1 bụ bioactive polypeptide dịpụrụ adịpụ ma sachaa site na mkpụrụ nke thymosin 5, nke nwere amino acid 28. Thymus bụ akụkụ dị mkpa nke usoro ahụ ji alụso ọrịa ọgụ, nke na-emepụta ihe dị iche iche na-achịkwa ọrụ mgbochi ọrịa, thymosin bụkwa otu n'ime ha. Site na nyocha miri emi nke ọrụ nke thymus, ndị mmadụ ejirila nwayọọ nwayọọ ghọta na ihe ndị na-arụ ọrụ n'ime ya nwere ike ịba uru maka ọgwụgwọ ọrịa dị iche iche.
Gịnị bụ usoro nke Thymosin Alpha-1?
Immunomodulation:
Thymosin Alpha-1 bụ ihe mgbanwe nzaghachi ndu nke nwere ike ịgbalite mkpụrụ ndụ dị iche iche na sistemu ahụ ji alụso ọrịa ọgụ. Ọ na-achịkwa ọrụ mgbochi site n'ịkwalite ọdịiche na maturation nke mkpụrụ ndụ T (Sjogren MH, 2004; Mao L, 2023). Kpọmkwem, Thymosin Alpha-1 nwere ike imetụta thymocytes site n'ịkwalite ọdịiche ha ma ọ bụ gbanwee ha ka ha bụrụ sel T na-arụ ọrụ.
Usoro mgbochi mkpali:
Na ọgwụgwọ COVID-19 oyi baa, Thymosin Alpha-1 na-eme ka mgbake sitere na oyi baa site na usoro mgbochi mkpali ya. Ọ nwere ike belata nzaghachi mkpali, kwalite mbelata nke COVID-19 ka oyi baa dị ka ahụ ọkụ na ike ọgwụgwụ, mee ka nnabata nke exudate dị mfe, ma mee ka mgbake sitere na oyi baa COVID-19 (Wang Z, 2023).
Kedu ka Thymalfasin si ebute apoptosis nke mkpụrụ ndụ tumo na ọgwụgwọ ọrịa kansa?
Ịkwalite ọrụ nke sel ndị na-alụso ọrịa ọgụ:
Thymalfasin bụ thymopeptide sịntetik nwere ọrụ na-eme ka ahụ ike dị elu. Ọ nwere ike ịkwalite mmetụta igbu mmadụ nke mkpụrụ ndụ na-alụso ọrịa ọgụ na mkpụrụ ndụ tumo, si otú ahụ na-ebute apoptosis nke mkpụrụ ndụ etuto na-apụtaghị ìhè. Dịka ọmụmaatụ, na microenvironment tumor, Thymalfasin nwere ike ịkwalite ọdịiche na maturation nke mkpụrụ ndụ T ma kwalite ọrụ nke mkpụrụ ndụ T. Dị ka akụkụ dị mkpa nke usoro ahụ ji alụso ọrịa ọgụ, mkpụrụ ndụ T nwere ike ịmata ma wakpo mkpụrụ ndụ tumor, na-ebute apoptosis nke mkpụrụ ndụ tumo site na ịhapụ ihe cytotoxic na ụzọ ndị ọzọ.
Na-ahazi nzaghachi mgbochi ọrịa:
Dị ka immunopotentiator, Thymalfasin nwere ike na-ahazi nzaghachi nke dịghịzi ahụ ma mee ka apoptosis nke mkpụrụ ndụ tumo. Ọ nwere ike ịkwalite nzaghachi mgbochi Th1. Mkpụrụ ndụ Th1 na-ezobe cytokines dị ka IFN-γ, nke nwere ike ime ihe na mkpụrụ ndụ tumo ma mee ka apoptosis ha pụta. Tụkwasị na nke ahụ, Thymalfasin nwekwara ike ịhazi ọrụ nke mkpụrụ ndụ ndị ọzọ na-alụso ọrịa ọgụ, dị ka ịkwalite ọrụ nke mkpụrụ ndụ NK. Mkpụrụ ndụ NK nwere ike igbu mkpụrụ ndụ tumor ozugbo ma mee ka apoptosis nke mkpụrụ ndụ tumo site na nzuzo cytokines na ụzọ ndị ọzọ [1].
Imeziwanye mgbochi immunosuppression n'oge ọgwụgwọ mgbochi tumor:
N'oge usoro ọgwụgwọ tumor, ndị ọrịa na-enwetakarị immunosuppression, nke ga-emetụta irè ọgwụgwọ tumor. Thymalfasin nwere ike melite immunosuppression nke a na-emepụta n'oge ọgwụgwọ ọrịa tumor, kwalite ikike nke usoro ahụ ji alụso ọrịa ọgụ ọgụ mkpụrụ ndụ tumo, ma si otú ahụ mee ka apoptosis nke mkpụrụ ndụ tumo. Dịka ọmụmaatụ, n'oge chemotherapy ma ọ bụ redio, usoro ahụ ji alụso ọrịa ọgụ ga-emebi ruo n'ókè ụfọdụ. Thymalfasin nwere ike ịkwalite mgbake na mmụba nke mkpụrụ ndụ na-alụso ọrịa ọgụ, meziwanye ọrụ nke usoro ahụ ji alụso ọrịa ọgụ, ma kwalite mmetụta igbu mmadụ na mkpụrụ ndụ tumo.
