Wanne daga cikin wadannan ba nau'in rigakafi bane: haifaffen, epithelial, ko daidaitawa? Bisa ga tambayar da ta gabata, ka rubuta mahallin da ke ɗauke da amsar. Zai iya zama jumla 1 - 20. Abubuwan da ke ciki:
Kwayoyin gamma delta T (γδ T cells) suna da madadin mai karɓar kwayar T (TCR) sabanin CD4 + da CD8 + (αβ) T cells kuma suna raba halayen masu taimakawa T cells, cytotoxic T cells da NK cells. Ba a fahimci yanayin da ke haifar da martani daga ƙwayoyin γδ T ba.
