EBINTU BYONNNA N’AMAWULIRE GW’EBINTU EBIweereddwa KU MUTINDO GUNO BIKOZESEBWA KU KUSASANYA AMAWULIRE N’EBIKOLWA BY’OKUSOMESA.
Ebintu ebiweereddwa ku mukutu guno bigendereddwamu kunoonyereza mu kisenge (in vitro research) byokka. Okunoonyereza mu vitro (Olulattini: *mu ndabirwamu*, ekitegeeza mu bikozesebwa mu ndabirwamu) kukolebwa ebweru w’omubiri gw’omuntu. Ebintu bino si bya ddagala, tebikkiriziddwa kitongole kya Amerika ekivunaanyizibwa ku by’emmere n’eddagala (FDA), era tebirina kukozesebwa kuziyiza, kujjanjaba oba kuwonya mbeera yonna ya bujjanjabi, bulwadde oba bulwadde. Kikugirwa nnyo mu mateeka okuyingiza ebintu bino mu mubiri gw’omuntu oba ebisolo mu ngeri yonna.
1. Okukubaganya ebirowoozo
Kisspeptin ye neuropeptide eriko enkodi y’obuzaale bwa Kiss1, okusinga eraga mu arcuate nucleus ne preoptic area ya hypothalamus. Kikola kinene mu kulungamya enkola y’okuzaala era kikola ng’ekikulu ekilungamya waggulu w’omugga ogw’ekisiki kya hypothalamic-pituitary-gonadal (HPG). Kisspeptin yeekwata ku G protein-coupled receptor 54 (GPR54), n’ekola amakubo agawerako agalaga obubonero okulungamya enkola y’okuzaala. Ekimu ku biraga okutandika kw’obuvubuka kwe kufulumya obusimu obufulumya gonadotropin (GnRH) mu ngeri ey’okukuba obusimu obuyitibwa hypothalamic GnRH neurons, era kisspeptin ekola ng’ekitundu ekikulu eky’okulungamya waggulu w’obusimu bwa GnRH, nga kikola kinene mu kukula kw’ekisiki ky’okuzaala.
Ekifaananyi 1 Enkola y’okukola kw’obutoffaali bwa kisspeptin.
2. Omulimu
Okulungamya entandikwa y’obuvubuka: Mu binyonyi ebiyonka, okwolesebwa kwa kisspeptin n’ekirungo kyayo GPR54 kweyongera nnyo nga obuvubuka tebunnatandika. Kikola obusimu bwa GnRH, ne kitumbula okufulumya GnRH mu ngeri ey’okukuba era bwe kityo ne kitandika okuvubuka. Mu bantu n’ebisolo ebirala ebiyonka, obutabaawo bubonero bwa kisspeptin kivaako obulwadde bwa hypogonadism olw’obutafulumya gonadotropin obutamala, bwe kityo ne kikosa entandikwa ya bulijjo ey’obuvubuka.
Okulungamya okufulumya obusimu bw’okuzaala: Kisspeptin asitula endwadde z’omu lubuto (anterior pituitary gland) okufulumya ebirungo ebiyitibwa gonadotropins, omuli obusimu obusitula enkwaso (FSH) ne luteinizing hormone (LH). Kino kituukibwako nga twongera ku kusengejja GnRH, nga kino nakyo kisitula obutoffaali bw’omu lubuto obw’omu maaso okusengejja n’okufulumya FSH ne LH, bwe kityo ne kitereeza enkola y’ennyindo, ne kitumbula okusengejja obusimu obuyitibwa gonadal steroid hormones, n’okwanguyiza enkula y’obutoffaali bw’obuwuka.
Okufuga enzirukanya y’okuzaala: Mu bisolo ebikazi, kisspeptin yeetaba mu kulungamya enzirukanya y’ensonga oba estrous cycle. Mu kiseera ky’okugenda mu nsonga, obusimu obuyitibwa kisspeptin neurons buba buwulize nnyo ku kulungamya okuddamu okukolebwa estrogen. Emiwendo gya estrogen bwe girinnya, emirimu gy’obusimu bwa kisspeptin gyeyongera, ekyongera okutumbula okufulumya GnRH, ne kivaako LH okulinnya, n’okuleeta eggi. Mu bisolo ebizaala mu sizoni ng’endiga, okwolesebwa n’emirimu gy’obusimu bwa Kisspeptin bikyuka n’enjawulo mu sizoni, ne kikosa okufulumya GnRH era bwe kityo ne kitereeza sizoni y’okuzaala.
Okwetaba mu nkola z’omubiri ezikwatagana n’okuzaala: Kisspeptin tekoma ku kukwata butereevu ku kitundu ky’omubiri ekiyitibwa gonadal axis wabula era yeetaba mu nkola endala ez’omubiri ezikwata ku kuzaala. Mu nkwaso, okwolesebwa kwa Kisspeptin n’ebigikwata kukwatagana nnyo n’enkula y’enkwaso, okukula, n’okufulumya enkwaso. Kikwata ku kukula kw’enkwaso n’okukola obusimu bwa steroid nga kitereeza obubonero bwa endocrine ne paracrine obw’omu kitundu mu nkwaso. Mu nseke, Kisspeptin era eyinza okwetaba mu kulungamya ensengekera y’ensigo n’okufulumya eddagala ly’obusimu obuyitibwa testosterone.
3. Okusaba
Obujjanjabi bw’obutazaala bw’abakyala: Mu kujjanjaba obutazaala bw’abakyala, Kisspeptin eraga omugaso oguyinza okukozesebwa. Ku balwadde abalina obuzibu mu kufulumya enkwaso oba obutafulumya gonadotropin obutamala olw’obutakola bulungi mu hypothalamic-pituitary, okugaba Kisspeptin oba analogues zaayo okuva ebweru kiyinza okuzzaawo enkola y’enkwaso eya bulijjo nga kisitula okufulumya GnRH ne gonadotropin. Okugeza, mu kunoonyereza okumu mu bujjanjabi, obujjanjabi n’ekirungo kya Kisspeptin analogues mu balwadde abalina obulwadde bwa functional hypothalamic amenorrhea bwazuulibwa nga buleeta okweyongera kw’okufulumya LH ne FSH, ng’abalwadde abamu baddamu okufulumya eggi n’okugenda mu nsonga.
Okulongoosa enkola y’okuzaala kw’abasajja: Mu by’obulamu bw’okuzaala kw’abasajja, Kisspeptin era erina okukozesebwa okusuubiza. Ku balwadde abasajja abalina oligoasthenozoospermia oba hypogonadism eva ku butafulumya gonadotropin obutamala, obujjanjabi bwa Kisspeptin buyinza okulongoosa omutindo n’obungi bw’ensigo nga butumbula okufulumya GnRH ne gonadotropins, bwe kityo ne kyongera ku kufulumya testosterone. Okunoonyereza ku bisolo kulaga nti okuweebwa Kisspeptin kiyinza okwongera ku bungi bwa testosterone mu bisolo ebisajja, okutumbula enkwaso, n’okutumbula obusobozi bw’okuzaala.
Tekinologiya w’okuzaala ayambibwako: Mu nkola ya in vitro fertilization-embryo transfer (IVF-ET), okufuga obulungi enkwaso z’abakyala n’obusimu kikulu nnyo. Kisspeptin esobola okukola nga ekigendererwa ky’eddagala eppya okulongoosa enkola z’okuyingiza eggi. Nga tulungamya ekkubo ly’obubonero bwa Kisspeptin, kiyinza okusoboka okufuga obulungi enkula y’enkwaso n’okufulumya eggi, okulongoosa emiwendo gy’okuggya amagi n’omutindo gw’embuto, bwe kityo ne kyongera ku buwanguzi bwa IVF-ET.
4. Okumaliriza
Mu bufunze, Kisspeptin etuwa enkola empya ez’okutumbula enkola y’okuzaala mu bujjanjabi bw’okuzaala kw’abantu.
