Of mice and the MHC
Article Abstract:
New research by C.J. Manning and colleagues seems to establish that major histocompatibility complex (MHC) plays a role in kin-recognition in mice. Nursing female mice generally nest in pairs or larger numbers, nursing each other's pups indiscriminately. Females choose nesting partners that are similar to them at the MHC locus, probably by odor. It is not clear that such a strategy is a response to selection pressures, as different nesting scenarios can produce either an advantage or disadvantage to associating with kin.

Green beard as death warrant
Article Abstract:
Research undertaken among the red fire ant, Solenopsis invicta, has shed new light on the theory of a green-beard gene. This theory indicates that genes can spread by displaying an observable and distinctive trait, by distinguishing between those who show the trait and those who do not and by being altruistic to those who do. The research shows that it is possible that genotype-specific execution of queen ants is a trait evolved by worker ants to allow polygyny in some nests.

Tetramer data reinterpreted
Article Abstract:
A chemically crosslinked complex including murine major histocompatibility complex (MHC) class I heavy chains and beta-2-microglobulins (beta-2-m) may not be a post-translationally put together MHC class I tetramer as was recently hypothesized. Another interpretation of the data includes the possibility that a critical lysine residue affects the crosslinker after the covalent crosslinking of HC and beta-2-m.
