distinguish Release factor A releasinghormone or releasing factor is a hormone whose main purpose is to control the release of another hormone. The main releasing hormones secreted by the hypothalamus are Thyrotropin releasinghormone TRH , Corticotropin releasinghormone CRH , Gonadotropin releasinghormone GnRH , Growthhormonereleasinghormone GHRH , Two other factors are also classed as releasing hormones, although they in fact inhibit pituitary hormone release Somatostatin , Dopamine . For example, TRH is released from the hypothalamus in response to low levels of secretion of thyroid stimulating hormone TSH from the pituitary gland . The TSH in turn is under feedback control by the thyroid hormones Thyroxine T4 and Triiodothyronine T3 . When the levels of TSH are too high, they feed back on the brain to shut down the secretion of TRH. Synthetic TRH is also used by physicians as a test of TSH reserve in the pituitary gland as it should stimulate the release of TSH and prolactin from this gland. Releasing hormones are sometimes known as liberins. For example, TRH may be known as thyroliberin. Inhibiting hormones may be known as statins. For example, dopamine which inhibits prolactin release may be called prolactostatin. Mechanism Releasing hormones increase or, in case of inhibitory factors, decrease the intracellular concentration of calcium Ca sup 2 sup , resulting in vesicle fusion of the respective primary hormone. For GnRH, TRH and GHRH the increase in Ca sup 2 sup is achieved by the releasinghormone coupling and activating G protein coupled receptors coupled to the Gq ... 11 Fulltext .

Prolactin releasinghormone , also known as PRLH, is a hypothetical human hormone or hormonereleasing factor. Existence of this factor has been hypothesized as prolactin is the only currently known hormone for which almost exclusively negative regulating factors are known such as dopamine , Leukemia inhibitory factor LIF , some prostaglandins but few stimulating factors. While many PRL stimulating and enhancing factors are well known such as TRH , oxytocin , steroid hormones those have primary functions other than stimulating prolactin release and the search for hypothetical releasing factor or factors continues. The PRLH prolacting releasing peptide identified in 1998 was a candidate for this function, however as of 2008 it appears its function is not yet completely elucidated. ref name Lin 2008 cite pmid 18204826 ref Reflist Category Human hormones Molecular cell biology stub ... more details
A gonadotropin releasinghormone analogue GnRH analogue or analog , also known as a luteinizing hormonereleasinghormone agonist LHRH agonist or LHRH analogue is a synthetic peptide medication drug modeled after the human hypothalamus hypothalamic gonadotropin releasinghormone GnRH . A GnRH analogue is designed to interact with the GnRH Receptor biochemistry receptor and modify the release of pituitary gonadotropin s Follicle stimulating hormone FSH and LH for therapeutic purposes. Shortly after the discovery of GnRH by Nobel laureates Roger Guillemin Guillemin and Andrew V. Schally Schally researchers tried to modify the GnRH decapeptide with the intent to synthesize stimulating and blocking variants. Two types of analogues have to be distinguished Agonists main Gonadotropin releasinghormone agonist A gonadotropin releasinghormone agonist GnRH agonist is an analogue that activates the GnRH receptor resulting in increased secretion of FSH and LH. Initially it was thought that agonists could be used as potent and prolonged stimulators of pituitary gonadotropin release, but it was soon recognized that agonists, after their initial stimulating action termed a flare effect eventually caused a paradoxical and sustained drop in gonadotropin secretion. This second effect was termed downregulation and can be observed after about 10 days. While this phase is reversible upon stopping the medication, it can be maintained when GnRH agonists use is continued for a long time. Antagonists main Gonadotropin releasinghormone antagonist A gonadotropin releasinghormone antagonist GnRH antagonist is an analogue that blocks the GnRH receptor resulting in an immediate drop in gonadotropin FSH, LH secretion. The GnRH antagonist is primarily used in IVF treatments to block natural ovulation. All GnRH analogues are contraindicated in pregnancy pregnancy category X . References Speroff L, Glass RH, Kase NG.

Gonadotrophin releasinghormone GnRH antagonists Receptor biochemistry receptor blockers are a class of compounds that are similar in structure to natural GnRH a hormone made by neurons in the hypothalamus but that have an antagonistic effect. GnRH antagonists are peptide molecules that are made up multiple, often synthetically produced amino acids . GnRH antagonists compete with natural GnRH for binding to GnRH receptors, thus decreasing or blocking GnRH action in the body. Mode of action GnRH antagonists competitively and reversibly bind to GnRH receptors in the pituitary gland , blocking the release of luteinising hormone LH and follicle stimulating hormone FSH from the pituitary. ref Broqua ... gonadotropin releasinghormone antagonist degarelix.

A Corticotropin releasinghormone antagonist is a specific type of receptor antagonist which blocks the receptor sites for Corticotropin releasinghormone also known as Corticotropin releasing factor CRF , blocking therefore the consequent secretions of ACTH and cortisol . There are four subtypes of this receptor known at present, defined as CRF 1, CRF 2a, CRF 2b and CRF 2g. Three of these receptors are expressed only in the brain, CRF 1 in the cortex and cerebrum, CRF 2a in the lateral septum and hypothalamus and CRF 2g in the amygdala. CRF 2b is expressed in the choroid plexus and cerebral arterioles in the brain, but is mainly expressed peripherally, on the heart and skeletal muscle tissue. ref McCarthy JR, Heinrichs SC, Grigoriadis DE.

Several antagonists for this receptor have been developed and are widely used in research, with the best known agents being the selective CRF 1 antagonist antalarmin and a newer drug pexacerfont , although several other ligands for this receptor are used in research, such as LWH 234, CP 154,526 , NBI 27914 and R 121,919.

A gonadotropin releasinghormone agonist GnRH agonist , GnRH A is a synthetic peptide modeled after the hypothalamic neurohormone GnRH that interacts with the gonadotropin releasinghormone receptor to elicit its biologic response, the release of the pituitary hormones Follicle stimulating hormone FSH and Luteinizing hormone LH . GnRH agonists are pregnancy category X drugs. Flare effect and downregulation Agonists do not quickly dissociate from the GnRH receptor. As a result initially there is an increase in FSH and LH secretion so called flare effect . However after about ten days a profound hypogonadal effect i.e. decrease in FSH and LH is achieved through receptor downregulation by internalization of receptors. Generally this induced and reversible hypogonadism is the therapeutic goal. Agonists with double and single substitutions GnRH agonists are synthetically modeled after the natural GnRH decapeptide with specific amino acid substitutions typically in position 6 and 10. These substitutions inhibit rapid degradation. Agonists with 2 substitutions include leuprolide Lupron, Eligard buserelin Suprefact, Suprecor nafarelin Synarel histrelin Supprelin LA, Vantas goserelin Zoladex deslorelin Suprelorin, Ovuplant Triptorelin is an agonist with only a single substitution at position 6. gallery Image Leuprorelin.svg Leuprolide Image Buserelin.svg Buserelin Image Nafarelin.svg Nafarelin Image Histrelin.svg Histrelin Image Goserelin.svg Goserelin Image Deslorelin.svg Deslorelin gallery Administration These medications can be administered intranasally , by Injection medicine injection , or by implant.
