Working memory representations are not hard copies of sensory information, even in early visual cortex, but can be recoded into more abstract and goal-directed formats aligned to behavioral goals.
Depletion of the TGFβ signal-transducer, SMAD4, in granulosa cells of growing follicles reduces the number of filopodia, termed transzonal projections, that stably attach to and mediate communication with the oocyte.
Alterations of DNA methylation were associated with articular cartilage degeneration in hemophilic arthropathy, and aberrant methylation and expression of TNXB promote blood-induced chondrocyte apoptosis by regulating AKT activation.
Transgenic zebrafish generated by targeted genomic integration distinguish neuronal subtypes in the nucleus incertus that differ in their connections and functional properties.

Enteric bacteria associated with bloodstream infections are attracted to human serum through L-serine and the chemoreceptor Tsr, and in an enterohemorrhagic lesion model use chemotaxis to invade damaged vasculature.
