Intrauterine Human Chorionic Gonadotrophins (hCG) and Endometrial Treg Cells

2014-08-27 03:16:07 | BioPortfolio

Summary

Intrauterine injection of hCG around the time of implantation may increase endometrial Treg cells and improve implantation. It has been demonstrated that regulatory T cells expand during pregnancy. hCG was found to be secreted by the embryo immediately after fertilization and has chemoattractant properties to Treg cells.

Description

Aim of the work:

To study the effect of intrauterine injection of human chorionic gonadotrophin on the endometrial T regulatory cells (Treg cells)and the electromicroscopic endometrial characteristics.

Background:

It has been demonstrated that regulatory T cells expand during pregnancy and are present at the feto-maternal interface at very early stages in pregnancy.

Rational:

Intrauterine injection of hCG around the time of implantation may increase endometrial Treg cells and improve implantation.

Methods:

Intrauterine injection of 100 IU hCG will be done followed by endometrial biopsy to check for Treg cells and pinopodes.

Poor Ovarian Stimulation Response in In Vitro Fertilization (IVF) Program

The aim of this study is to assess the role of AMH in prediction of poor ovarian response as well as the relation between ESR2 (+1730G>A) (rs4986938), FSHR p.Thr307Ala (c.919A>G, rs6165) a...

Triggering of Follicular Maturation

The follicular phase of the menstrual cycle involves the hourly release of gonadotropin-releasing hormone, which binds to receptors on the gonadotropes. This results in the secretion of fo...

The magnitude of ovulation rate (OR) after hormonal induction in sheep should be considered when prolific genotypes are used. We investigated for the first time the effect of the Vacaria allele and it...

Medical and Biotech [MESH] Definitions

The beta subunit of luteinizing hormone. It is a 15-kDa glycopolypeptide with structure similar to the beta subunit of the placental chorionic gonadatropin (CHORIONIC GONADOTROPIN, BETA SUBUNIT, HUMAN) except for the additional 31 amino acids at the C-terminal of CG-beta. Full biological activity of LH requires the non-covalently bound heterodimers of an alpha and a beta subunit. Mutation of the LHB gene causes HYPOGONADISM and infertility.

The beta subunit of human CHORIONIC GONADOTROPIN. Its structure is similar to the beta subunit of LUTEINIZING HORMONE, except for the additional 30 amino acids at the carboxy end with the associated carbohydrate residues. HCG-beta is used as a diagnostic marker for early detection of pregnancy, spontaneous abortion (ABORTION, SPONTANEOUS); ECTOPIC PREGNANCY; HYDATIDIFORM MOLE; CHORIOCARCINOMA; or DOWN SYNDROME.

Trophoblastic hyperplasia associated with normal gestation, or molar pregnancy. It is characterized by the swelling of the CHORIONIC VILLI and elevated human CHORIONIC GONADOTROPIN. Hydatidiform moles or molar pregnancy may be categorized as complete or partial based on their gross morphology, histopathology, and karyotype.

A gonadotropic glycoprotein hormone produced primarily by the PLACENTA. Similar to the pituitary LUTEINIZING HORMONE in structure and function, chorionic gonadotropin is involved in maintaining the CORPUS LUTEUM during pregnancy. CG consists of two noncovalently linked subunits, alpha and beta. Within a species, the alpha subunit is virtually identical to the alpha subunits of the three pituitary glycoprotein hormones (TSH, LH, and FSH), but the beta subunit is unique and confers its biological specificity (CHORIONIC GONADOTROPIN, BETA SUBUNIT, HUMAN).

Inability to reproduce after a specified period of unprotected intercourse. Reproductive sterility is permanent infertility.
