Dopaminergic input shapes activity of specialized amygdala inhibitory cell clusters by ionotropic and metabotropic mechanisms that may enable their selection during distinct fear-related behavioral states.
Male C. elegans die through two distinct mechanisms – mating-induced germline activation, and potent male pheromone toxicity – but the latter is unique to males of androdioecious species (made up of hermaphrodites and males).
The B-1a cell heavy chain antibody repertoire differs dramatically from the follicular and marginal zone B cell repertoire and is defined by distinct mechanisms driven by self antigens rather than antigens derived from the microbiota.
The multiple component mechanisms of extra-classical receptive field modulation, with distinct dynamics, discovered in the monkey visual cortex have important implications for understanding contextual perceptual processing.
ME31B is a general repressor of gene expression in the Drosophila early embryo, repressing translation before the maternal-to-zygotic transition and stimulating mRNA decay after activation of the zygotic genome.
Building on previous work (Diao et al., 2012), we show that the mechanism by which complexin suppresses spontaneous fusion is distinct from the mechanism by which it synchronizes Ca2+-triggered fusion.
Stem cell migration underlies head regeneration in the cnidarian (jellies and their kin) Hydractinia, but the regeneration of other body parts is based on the gradual transformation of one tissue type into another.
