Recent Advances in Mammalian Olfactory Receptor Function and Structure
Olfactory receptors (ORs), a subset of G protein‐coupled receptors (GPCRs), mediate odor detection in sensory neurons and regulate diverse physiological functions across tissues. Their roles in metabolism, immunity, and neural processes underscore their therapeutic relevance. Recent high‐resolution Cryo‐EM studies have unveiled OR activation mechanisms,

Update on mammalian sperm capacitation : how much does the horse differ from other species?
In contrast to various other mammalian species, conventional in vitro fertilization (IVF) with horse gametes is not reliably successful. In particular, stallion spermatozoa fails to penetrate the zona pellucida, most likely due to incomplete activation ...

Essential role of CFTR in PKA-dependent phosphorylation, alkalinization, and hyperpolarization during human dperm capacitation [PDF]
Mammalian sperm require to spend a limited period of time in the female reproductive tract to become competent to fertilize in a process called capacitation.

Abstract Background Ion channels are essential for differentiation and maturation of germ cells, and even for fertilization in mammals. Different types of potassium channels have been identified, which are grouped into voltage‐gated channels (Kv), ligand‐gated channels (Kligand), inwardly rectifying channels (Kir), and tandem pore domain channels (K2P).

Exposure to Cadmium Impairs Sperm Functions by Reducing CatSper in Mice
Background: Cadmium (Cd), a common environmental heavy metal and endocrine disruptor, is known to exert toxic effects on the testes. However, the mechanisms accounting for its toxicity in mature spermatozoa remain unclear.

CCR6 is required for ligand-induced CatSper activation in human sperm
CatSper channel has been considered the principal sperm Ca2+ channel responsible for the cytosolic Ca2+ elevation required for various sperm functions necessary for fertilization [1-4]. However, the mechanism underlying the activation of CatSper channel by various physiological ligands remain incompletely understood.
