From a meeting report in #JournalImmunology:
"He (Jonathan Kagan) showed that old mice lose their naive CD8+ T cell repertoire, and the absence of CD8+ T cells in young mice reduces their survival rate. Protective immunity against cancer rises from CD4+ T cells in old mice, whereas CD8+ T cells are responsible for antitumor immunity in young mice."

"In memory T cells, the frequency of CXCR5+CXCR3+CCR6− circulating follicular Th1 was positively correlated with RBD-specific Ab-secreting B cells. For the response to variant RBDs, although 60–80% of memory B cells could bind to the omicron RBD, their avidity was low, whereas memory T cells show an equal response to the omicron spike."

"The human MPYS gene is highly heterogeneous (9, 10). Approximately 50% of Americans carry a non–wild-type (WT) (R232) MPYS allele (9). R71H-G230A-R293Q (HAQ) is the second most common human MPYS allele carried by ∼25% of Americans and ∼63% of East Asians (EAS) (9). Surprisingly, we recently found that HAQ knock-in mice do not respond to CDNs in vivo (11). In corroboration, Mogensen and colleagues (12) reported that homozygous HAQ MPYS/STING was enriched in HIV-infected individuals that were long-term nonprogressors."
