Gulu limodzi, lotchedwa T-lymphocyte kapena T-cell, limasamukira kumtundu wotchedwa thymus.

Mothandizidwa ndi mahomoni, amakula m'mitundu ingapo, kuphatikiza othandizira, akupha, ndi ma suppressor. Mitundu yosiyanayi imagwirira ntchito limodzi kuti iukire olanda achilendo. 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.
