Beta-chemokine, regulated on activation and normally T-cell expressed and presumably secreted (RANTES), is present in both the male and female genital tract fluids where its levels increase in diseases related to infertility, such as endometriosis and male genital tract infections. beta-Chemokine receptors (CCR3 and CCR5) are expressed on freshly ejaculated human sperm cells and a sperm chemoattractant effect for RANTES has been reported. No information exists on other possible roles of RANTES… 

Figures from this paper

Beta-chemokine receptor CCR5 in human spermatozoa and its relationship with seminal parameters.
TLDR
The percentage of CCR5-positive spermatozoa may vary under conditions associated with changes in membrane architecture and spermatozosa showed large intracellular pools of the receptor.
CCL20-CCR6 axis directs sperm–oocyte interaction and its dysregulation correlates/associates with male infertility‡
TLDR
Findings of the present study suggest that CCR6-CCL20 interaction may represent an important factor in directing sperm–oocyte interaction.
Different locations of RANTES and its receptors on mouse epididymal spermatozoa.
TLDR
RANTES and its receptors were not in the same sperm location, suggesting that RANTES binding to mouse epididymal spermatozoa is independent of CCR1, CCR3 and CCR5.
Protein tyrosine phosphorylation of the human sperm head during capacitation: immunolocalization and relationship with acquisition of sperm-fertilizing ability.
TLDR
Head TP is a subsurface event occurring early during capacitation and is closely related to acquisition of the ability to display P-stimulated acrosome reactions (ARs) and to penetrate zona-free hamster oocytes, whereas the able to fuse with oolemma and to decondense is a later capacitation-related event.
Construction and Analysis of the Cell Surface's Protein Network for Human Sperm-Egg Interaction
TLDR
This study built the first protein interaction network of human sperm-egg binding and fusion proteins that consists of 84 protein nodes and 112 interactions and showed that the ADAM2 may mediate interaction between two essential factors CD9 and IZUMO1.
Pathophysiological factors and genetic association in endometriosis
TLDR
A strong inflammatory component in endometriosis is found, which may affect the ovarian reserve and lead to infertility problems and may at least partly be regulated by inflammatory mediators.
The effects of an in utero exposure to 2,3,7,8-tetrachloro-dibenzo-p-dioxin on male reproductive function: identification of Ccl5 as a potential marker
TLDR
A decrease in Ccl5/Rantes RNA levels and a transitory decline in sperm reserves in the testes of rats of TCDD-dosed dams is demonstrated.
Endometriosis‐Associated Infertility: Double Intrauterine Insemination Improves Fecundity in Patients Positive for Antiendometrial Antibodies

The effect of RANTES on human sperm chemotaxis.
TLDR
It was demonstrated that mRNA for the RANTES receptors CCR-1 and CCR -5 are present in human sperm and RantES is involved in the chemotactic effect of FF in vitro.
The human sperm acrosome reaction: physiology and regulatory mechanisms. An update.
TLDR
A novel protein, termed SAA-1, that was first detected on human spermatozoa is discussed with respect to its potential role as a regulatory protein closely involved in the initiation of the acrosome reaction.
Capacitation as a regulatory event that primes spermatozoa for the acrosome reaction and fertilization.
TLDR
The reversibility of some of the mechanisms leading to sperm capacitation may be a very important aspect of the fine regulation and perfect timing of this process.
Effect of platelet-activating factor on motility and acrosome reaction of human spermatozoa.
TLDR
It is found that short-term incubation with PAF significantly enhanced total and progressive sperm motility as well as acrosome reaction and a possible physiological role for PAF in fertilization is indicated.
Human sperm capacitation and the acrosome reaction.
TLDR
The processes of capacitation and the acrosome reaction are proposed to function in control of the activation/release of acrosomal enzyme(s) involved in sperm penetration through the zona pellucida.
Beta‐chemokine receptors 5 and 3 are expressed on the head region of human spermatozoon
TLDR
Both CCR5 and CCR3 expressed on the sperm cell surface may be involved in HIV‐1 adhesion to spermatozoa, thus allowing these cells to perform as virion cellular carriers during sexual transmission of HIV‐ 1 infection.
The inhibition of the human sperm phosphatidylinosytol 3-kinase by LY294002 does not interfere with sperm/oocyte interaction.
TLDR
Results indicate that the inhibition of PI3K by LY 294002 does not interfere with sperm interaction with oocytes, noteworthy in the view of a possible clinical use of LY294002 as an in vitro stimulator of the sperm motility of asthenozoospermic patients for assisted reproduction techniques.
Detection of a short CCR5 messenger RNA isoform in human spermatozoa.
TLDR
Using reverse transcription and real-time quantitative polymerase chain reaction (RQ-PCR) analysis, it is found that the CCR5 mRNA isoform in human spermatozoa consists of exons 3 and 4, and is shorter than the transcript in leukocytes.
Progesterone triggers a wave of increased free calcium during the human sperm acrosome reaction.
TLDR
These results are the first to detect a ligand-mediated Ca2+ wave in sperm and to suggest that Cl- efflux influences Ca2+.
How do sperm swim? Molecular mechanisms underlying sperm motility.
TLDR
The present review focuses on the molecular mechanisms and factors involved in the development and maintenance of sperm motility, and shows some preliminary data obtained in the laboratory on the involvement of the phosphatydilinositol 3-kinase and the A kinase anchoring protein (AKAP3) in regulation of motility in human spermatozoa.
