CD4+ T cells re-wire granuloma cellularity and regulatory networks to promote immunomodulation following Mtb reinfection
Abstract
Th1 CD4+ T cells mediate protective antiMtb immunity across biological systems
and organisms. Bromley, Ganchua, et al.
demonstrate that CD4+ T cells regulate
immune tone in TB granulomas and are
necessary for immune recall and
protection against reinfection. Following
reinfection, CD4+ T cells facilitate the
development of a growth restrictive niche
via the induction of immuno-modulatory
genes and cellular interaction networks.
