Females' regenerating advantage

M en might build more muscle, but women are better at keeping what they have, if results from Deasy et al. (page 73) are any indication. The group shows that female muscle stem cells are better than their male counterparts at regenerating lost muscle. The authors were led into the realm of muscle and sex when they realized that they were relying heavily on cell lines derived from female mice to...

Animal Survival Efficiently Kill Glioblastoma and Prolong Have a Functional Activation Advantage To NK Cells with KIR2DS2 Immunogenotype

NK cells with KIR2DS2 immunogenotype have a functional activation advantage to efficiently kill glioblastoma and prolong animal survival.

Glioblastomas (GBMs) are lethal brain cancers that are resistant to current therapies. We investigated the cytotoxicity of human allogeneic NK cells against patient-derived GBM in vitro and in vivo, as well as mechanisms mediating their efficacy. We demonstrate that KIR2DS2 immunogenotype NK cells were more potent killers, notwithstanding the absence of inhibitory killer Ig-like receptor (KIR)-...

The fitness consequences of honesty: Under-signalers have a survival advantage in song sparrows.

How honest or reliable signaling can evolve and be maintained has been a major question in evolutionary biology. The question is especially puzzling for a particular class of signals used in aggressive interactions: threat signals. Here, we report a study on song sparrows (Melospiza melodia) in which we assayed males with playbacks on their territories to quantify their aggressiveness (flights ...
