Cov ntsiab lus kev paub
Hauv kev tswj hwm kev ua me nyuam, nws lub zog tshwm sim hauv "micro- ua kom muaj zog thiab tswj tau dav." Tsuas yog ib koob tshuaj tsawg ntawm 1-10 nmol / kg yog xav tau kom sai sai ua rau lub pulsatile secretion ntawm gonadotropin- tso cov tshuaj hormones (GnRH) los ntawm kev khi rau GPR54 receptor, nce luteinizing hormone (LH) thiab follicle-stimulating hormone (FSH) qib los ntawm 30%-50%, muaj. activating lub synthesis ntawm testosterone los yog estradiol. Cov ntaub ntawv kho mob qhia tau hais tias kev txhaj tshuaj Kisspeptin-10 rau cov neeg mob hypothalamic tsis ua haujlwm tuaj yeem rov ua haujlwm HPG axis hauv 2 teev, ua tiav 60% kev ua tau zoo hauv kev kho tus txiv neej oligospermia thiab nce qhov kev vam meej ntawm ovulation induction hauv cov poj niam los ntawm 40%, tsis muaj kev phiv tseem ceeb, ua kom pom nws cov yam ntxwv "potency" tsawg.https://www.fiercerawsource.com/peptides/premium-high-purity-peptides-kisseptin.html
Nws lub zog kuj tseem cuam tshuam rau hauv nws lub zog nkag mus ntawm "hla-txoj kev sib koom ua ke." Ntxiv nrog rau kev yug me nyuam, Kisspeptin tuaj yeem txhim kho cov tshuaj insulin los ntawm txoj hauv kev hauv lub paj hlwb, txhim kho cov ntshav qabzib tswj kev ua haujlwm ntawm cov neeg rog rog los ntawm 25%; ib txhij, nws activates hlwb nqi zog txoj kev, alleviating ntxhov siab vim thiab kev nyuaj siab. Hauv cov kev sim cuam tshuam, cov neeg kawm uas tau txais tshuaj tsuag qhov ntswg Kisspeptin pom qhov txo qis ntawm 35% hauv cov qhab nia phobia. Qhov ntau-seem thiab muaj peev xwm tswj hwm no tshwm sim los ntawm kev nthuav dav ntawm nws cov receptors hauv cov chaw ua me nyuam, metabolic, thiab kev xav, thiab nws cov teeb liab transduction efficiency yog 5-10 npaug ntawm cov tshuaj hormones zoo tib yam.
Hauv kev siv tshuaj kho mob, nws "dose-dependent potency" yog qhov tseem ceeb tshwj xeeb. Tsawg koob tshuaj (<5 nmol/kg) can gently regulate the reproductive axis, making it suitable for fertile couples; medium- to high doses (10-20 nmol/kg) can strongly activate the HPG axis, used to treat hypogonadism; supraphysiological doses can temporarily desensitize receptors, achieving reversible "downregulation," providing a new approach for assisted reproductive technologies. Compared to traditional hormone therapy, Kisspeptin's regulatory intensity is easier to control, and HPG axis function can recover rapidly after discontinuation, avoiding long-term dependence.
Nws yuav tsum raug sau tseg tias nws qhov kev siv zog cuam tshuam los ntawm tus kheej receptor qhia theem; Qee tus neeg tuaj yeem ntsib "kev ua haujlwm qis," yuav tsum tau hloov kho ntau npaum li cas los ntawm kev kuaj caj ces. Zuag qhia tag nrho, Kisspeptin, nrog rau nws cov txiaj ntsig tseem ceeb ntawm "kev ua haujlwm siab nrog tsawg npaum li cas thiab kev tswj xyuas meej," tau dhau los ua lub peev xwm molecule hauv kev tswj hwm endocrine. Nws lub zog tsis yog tsuas yog nyob rau hauv nws cov kev ua si lom neeg, tab sis kuj nyob rau hauv nws cov txiaj ntsig zoo thiab kev tswj hwm tus nqi ntawm lub cev.
