Potassium (K+) channels shape the response properties of neurons.

Acute stress impairs recall memory through the facilitation of long-term depression (LTD) of hippocampal synaptic transmission. The endogenous opioid system (EOS) plays essential roles in stress-related emotional and physiological responses. Specifically, behavioral studies have shown that the impairment of memory retrieval induced by stressful events involves the activation of opioid receptors. However, it is unclear whether signaling mediated by μ-opioid receptors (μRs), one of the three major opioid receptors, participates in acute stress-related hippocampal LTD facilitation.

In the central nervous system, the type I transmembrane glycoprotein NG2 (nerve-glia antigen 2) is only expressed by pericytes and oligodendrocyte precursor cells (OPCs). Therefore, OPCs are also termed NG2 glia. Their fate during development has been investigated systematically in several genetically modified mouse models.

Successful reproduction in female mammals is precisely timed and must be able to withstand the metabolic demand of pregnancy and lactation.

Successful pregnancy requires the establishment of a complex dialogue between the implanting embryo and the endometrium. Knowledge regarding molecular candidates involved in this early communication process is inadequate due to limited access to primary human endometrial epithelial cells (EEC).

Touch and mechanical pain represent distinct, but interactive, modalities of mechanosensation. However, the molecular mechanisms underlying these mechanotransduction processes remain incompletely understood. Here, we show that deletion of the mechanically activated and rapidly adapting Piezo2 channel in a portion of the low-threshold mechanoreceptors and a majority of the IB4-positive nociceptors impairs touch but sensitizes mechanical pain in mice.

Zika virus (ZIKV) has recently been associated with birth defects and pregnancy loss after maternal infection. Because dengue virus (DENV) and ZIKV co-circulate, understanding the role of antibody-dependent enhancement in the context of pregnancy is critical. Here, we showed that the presence of DENV-specific antibodies in ZIKV-infected pregnant mice significantly increased placental damage, fetal growth restriction, and fetal resorption.

Abstract

Colon tumours are hierarchically organized and contain multipotent self-renewing cells, called Cancer Stem Cells<

In Drosophila, the clock that controls rest-activity rhythms synchronizes with light-dark cycles through either the blue-light sensitive cryptochrome (Cry) located in most clock neurons, or rhodopsin-expressing histaminergic photoreceptors. Here we show that, in the absence of Cry, each of the two histamine receptors Ort and HisCl1 contribute to entrain the clock whereas no entrainment occurs in the absence of the two receptors. In contrast to Ort, HisCl1 does not restore entrainment when expressed in the optic lobe interneurons.
