Frontiers in Immunology, 2023 It is known that sperm and seminal plasma (SP) affect uterine immunity. In cattle, artificial insemination enables breeding by depositing frozen and largely diluted sperm with a negligible amount of SP into the uterus.

Control of hyperactivation in sperm [PDF]
Human Reproduction Update, 2008 Sperm hyperactivation is critical to fertilization, because it is required for penetration of the zona pellucida. Hyperactivation may also facilitate release of sperm from the oviductal storage reservoir and may propel sperm through mucus in the oviductal lumen and the matrix of the cumulus oophorus.

Regulation of hyperactivation by PPP2 in hamster spermatozoa [PDF]
Reproduction, 2010 Abstract It has been widely accepted that serine/threonine protein phosphatases (PPPs) are associated with the regulation of sperm hyperactivation. In the present study, we examined the types of PPPs associated with the regulation of hamster sperm hyperactivation.

Diverse Control Mechanisms of the Interleukin-1 Cytokine Family
Frontiers in Cell and Developmental Biology, 2022 The majority of interleukin-1 (IL-1) family cytokines lack amino terminal secretion signals or transmembrane domains for secretion along the conventional biosynthetic pathway.

TRPV4 is the temperature-sensitive ion channel of human sperm
eLife, 2018 Ion channels control the ability of human sperm to fertilize the egg by triggering hyperactivated motility, which is regulated by membrane potential, intracellular pH, and cytosolic calcium.

Effects of aging and oviductal hormones on testes, epididymides, and sperm of hamster
Reproductive Medicine and Biology, 2022 Purpose Aging is a major cause of decreased fertility. Using hamster, we examined the effects of aging on testes, epididymides, and sperm. Additionally, we examined whether progesterone (P4), melatonin (Mel) and 5‐hydroxytryptamine (5‐HT) mitigated ...

Hyperactivated endolysosomal trafficking in melanoma
Oncotarget, 2015 Cutaneous melanoma is an increasingly frequent solid tumor that accounts for 80% of skin cancer-related deaths. Characterized by a complex and heterogeneous genetic background and a notorious functional plasticity, melanoma has shifted from a “black box” to a paradigm of how basic research can be successfully translated into significant improvements of

Regulation of hyperactivation of hamster spermatozoa by progesterone [PDF]
Reproductive Medicine and Biology, 2008 Aim: Although it is accepted that progesterone (P) induces acrosome reaction through non‐genomic regulation, it is not well known if P also affects hyperactivation of sperm.Methods: Hamster spermatozoa were hyperactivated by incubation for 4 h on modified Tyrode's albumin lactate pyruvate medium and recorded on a DVD via a charge‐coupled device ...

The Journal of Reproduction and Development, 2023 Progesterone (P) enhances spermatozoal hyperactivation, a capacitation event. Hyperactivation is associated with successful in vitro fertilization (IVF). In this study, we examined the effects of P on hyperactivation and IVF in mice.
