Transient exposure to calcium ionophore enables in vitro fertilization in sterile mouse models [PDF]

open access: yes, 2016
Mammalian sperm acquire fertilizing capacity in the female tract in a process called capacitation. At the molecular level, capacitation requires protein kinase A activation, changes in membrane potential and an increase in intracellular calcium ...

NK Cells Respond to Haptens by the Activation of Calcium Permeable Plasma Membrane Channels. [PDF]

open access: yes, 2016
Natural Killer (NK) cells mediate innate immunity to infected and transformed cells. Yet, NK cells can also mount hapten-specific recall responses thereby contributing to contact hypersensitivity (CHS). However, since NK cells lack antigen receptors that

Discovery and Characterization of Multiple Classes of Human CatSper Blockers

open access: yesChemMedChem, 2022
AbstractThe cation channel of sperm (CatSper) is a validated target for nonhormonal male contraception, but it lacks selective blockers, hindering studies to establish its role in both motility and capacitation. Via an innovative calcium uptake assay utilizing human sperm we discovered novel inhibitors of CatSper function from a high‐throughput ...

Molecular cloning, spatial and temporal expression analysis of CatSper genes in the Chinese Meishan pigs

open access: yesReproductive Biology and Endocrinology, 2011
Background Sperm ion channel proteins (CatSpers) are essential for sperm hyperactivated motility, and then penetration through the zona pellucida. The CatSper class of proteins have well been characterized in the mouse and human.

Effects of Fscb/Cabyr double gene knockout on reproductive capacity in male mice

open access: yesDi-san junyi daxue xuebao, 2021
Objective To evaluate the value of CABYR protein and its complex with FSCB in maintaining sperm fertilization ability and investigate the possible mechanism of physiological function of the coruplex by observing the natural fertility of Fscb/Cabyr double

Mouse sperm membrane potential hyperpolarization is necessary and sufficient to prepare sperm for the acrosome reaction [PDF]

open access: yes, 2012
Mammalian sperm are unable to fertilize the egg immediately after ejaculation; they acquire this capacity during migration in the female reproductive tract. This maturational process is called capacitation and in mouse sperm it involves a plasma membrane

Regulation and roles of Ca2+ stores in human sperm. [PDF]

open access: yes, 2015
[Ca(2)(+)]i signalling is a key regulatory mechanism in sperm function. In mammalian sperm the Ca(2)(+)-permeable plasma membrane ion channel CatSper is central to [Ca(2)(+)]i signalling, but there is good evidence that Ca(2)(+) stored in intracellular ...
