Amapereka chomwe chimatchedwa chitetezo chazomwe zimapangidwa ndi ma cell, chomwe chimatha kukhala chosowa mwa anthu omwe ali ndi HIV, kachilombo kamene kamayambitsa Edzi. HIV imawononga ndikuwononga ma T othandizira.
Gulu lina la ma lymphocyte limatchedwa B-lymphocyte kapena ma B maselo. Amakhwima m'mafupa ndipo amatha kuzindikira owukira akunja.
Maselo okhwima a B amayenda kudzera m'madzi amthupi kupita ku ma lymph node, ndulu, ndi magazi. M'Chilatini, madzi amthupi amadziwika kuti nthabwala. Chifukwa chake ma B-cell amapereka zomwe zimadziwika kuti humoral immune. Ma B-cell ndi T-cell onse amayenda momasuka m'magazi ndi ma lymph, kufunafuna olowerera akunja.
