Article Abstract

We aimed to analyze the influence of different cellular concentrations of boar sperm suspensions on the induction of capacitation and acrosome reaction. When spermatozoa were incubated at 100 or 200 mill/ml, significant increases in protein tyrosine phosphorylation in the p32 protein were observed, compared to those at 50 mill/ml. In addition, sperm concentration-dependent increases were observed in plasma membrane lipid disorganization (50 mill/ml vs. 200 mill/ml), induction of the acrosome reaction (50 mill/ml vs. 100 mill/ml and 200 mill/ml), and sperm viability (50 mill/ml vs. 100 mill/ml and 200 mill/ml). Our data indicate that an increase in sperm concentration stimulates the induction of capacitation and acrosome reaction in boars.

Phosphatidylserine translocation, cholesterol spatial distribution, and acrosome reaction reliably distinguish sperm capacitation from cryoinjury in bovine sperm.

Sperm capacitation is a critical process for successful fertilization, involving multiple regulated cellular changes. On the other hand, cryopreservation induces membrane changes that can mimic capacitation, potentially leading to misinterpretation of sperm function. Distinguishing true capacitation from cryoinjury remains challenging, as both share surface markers despite involving distinct mechanisms and impacts on fertilization.

Extracellular vesicles: key mediators in embryo production.

Nano-sized extracellular vesicles (EVs) possess a lipid bilayer and are secreted from cells into their surrounding environment. The transport of multiple biomolecules, including DNA together with RNA, microRNAs (miRNAs), lipids, proteins, and metabolites, happens through biofluids via EVs for intercellular communication. Extracellular vesicles play crucial roles during the embryo production (IVEP) process.

In mammals, sperm formation is completed in the seminiferous tubules within the testis, and sperm maturation occurs during the epididymal transit of the spermatozoa. Sperm morphology drastically changes when abnormal spermatozoa migrate from the testis to the epididymis. Detailed molecular mechanisms for sperm survival in the epididymis have not been determined yet.

The aim of this study was to analyze how recombinant rabbit NGF (Nerve Growth Factor) encapsulated in chitosan (rrβNGFch) affects sperm viability, motility, capacitation, acrosome reaction (AR), kinetic traits, and apoptosis after 30 min and 2 h of storage. Specific intracellular signaling pathways associated with either cell survival, such as protein kinase B (AKT) and extracellular signal-regulated kinases 1/2 (ERK1/2), or programmed cell death, such as c-Jun N-terminal kinase (JNK), were also analyzed. The results confirmed the effect of rrβNGFch on capacitation and AR, whereas a longer storage time (2 h) decreased all qualitative sperm traits.

Sperm-egg interactions involve a complex series of molecular events. Among these, the acrosome reaction (AR) is a prerequisite for sperm penetration, facilitating the exposure of multiple acrosomal proteins that enhance sperm binding or penetration of the outer layer of the egg; however, the specific molecules involved in this process vary across species. A disintegrin and metalloproteinase (ADAM) proteins are transmembrane glycoproteins that play a role in sperm-egg interactions, with notable differences among ADAM isoforms.
