IMMUNOGENETICS
Sex-Biased Aging Effects on Ig Somatic Hypermutation Targeting
SHM hot- and cold-spot biases are largely consistent between different age and sex groups.

The Invariant NKT Cell Response Has Differential Signaling Requirements during Antigen-Dependent and Antigen-Independent Activation
IL-12, IL-18, and TLRs are dispensable for TCR-dependent activation of iNKT cells.
During TCR-independent activation, IL-12 is necessary but not sufficient.
