▎ Nchọpụta GLP-2
Kedu ihe ndabere nyocha nke GLP-2?
GLP-2 bụ ọgwụ polypeptide sịntetik, mmepe ya sitere na nghọta miri emi nke oke nke GLP-1 agonists nnabata dị na ọgwụgwọ ụdị 2 metabolism na oke ibu. Ọ bụ ezie na ndị na-anabata GLP-1 egosilarị arụmọrụ dị mma na njikwa glucose ọbara na mbelata ibu arọ, ndị ọkà mmụta sayensị achọpụtala na ka ha na-arụ ọrụ GLP-1 receptor, mmetụta ha na-arụ ọrụ na onye na-anabata GIP adịghị ike, nke ruo n'ókè ụfọdụ na-egbochi mmetụta ọgwụgwọ ọgwụ. Ya mere, otu nyocha na mmepe na-agba mbọ imepụta ụdị ọgwụ ọhụrụ nke nwere ike ịgbalite ma GIPR na GLP-1R n'otu oge, na-atụ anya inweta njikwa glucose ọbara zuru oke ma dị irè na njikwa ibu [1]. .
N'ime usoro nyocha na mmepe nke GLP-2, ndị ọkà mmụta sayensị emeela ọtụtụ nyocha dị mkpa na nnwale ụlọ ọgwụ. Nke mbụ, n'ime usoro nyocha nke izizi, a tụlere njirimara ọgwụ GLP-2 nke ọma site na nnwale anụmanụ, na ikike ọ nwere na njikwa glucose ọbara na mbelata ịdị arọ ka enwetara. Nsonaazụ gosiri na GLP-2 nwere ike ibelata ọkwa glucose ọbara n'ụdị anụmanụ ma rụọ ọrụ nke ọma na njikwa ibu. Nchọpụta ndị a dị mma tọrọ ntọala siri ike maka ule ụlọ ọgwụ na-esote.
Mgbe nke ahụ gasịrị, GLP-2 banyere n'ọkwa nnwale ụlọ ọgwụ, gụnyere ule nke I, II, na III. N'ime oge ikpe nke mbụ, a na-enyocha nchekwa, nnabata, na njirimara ọgwụ ọgwụ, yana nsonaazụ gosipụtara na GLP-2 nwere ezigbo nchekwa na nnabata. Nnwale nke usoro nke abụọ nyochara ịdị irè na nchekwa nke usoro GLP-2 dị iche iche na ndị ọrịa nwere ụdị 2 metabolism, ma buru ụzọ kpebie oke dose ya dị mma. Ọnwụnwa ụlọ ọgwụ kachasị mkpa nke III, dị ka usoro ọmụmụ SURPASS, kpuchiri ọnụ ọgụgụ buru ibu nke ndị ọrịa nwere ụdị ọrịa shuga 2. Nsonaazụ gosiri na GLP-2 dị nnọọ elu karịa ndị agonists GLP-1 dị adị, dị ka GLP-1, n'ibelata glucose na ibu ọbara. Nsonaazụ nsonaazụ a nyere nkwado nkwado siri ike maka ngwa ahịa nke GLP-2 [1].
GLP-2 bụ polypeptide mejupụtara amino asịd 39, nke emezigharịrị n'ụdị amino asịd nke ọ bụla iji kwalite nkwụsi ike na arụmọrụ ya. Nhazi nhazi a pụrụ iche na-enyere GLP-2 aka ijikọ mmetụta nke homonụ incretin abụọ, GIP na GLP-1, n'ime otu molekul, ma mee ka ndị na-anabata homonụ na-etinye aka na njikwa glucose ọbara site na usoro omume abụọ. Kpọmkwem, GLP-2 nwere ike ime ma pancreas na sistemu ụjọ nke etiti. N'otu aka ahụ, ọ na-akwalite mmepụta insulin ma na-egbochi mwepụta glucagon, si otú a na-ebelata glucose ọbara n'ụzọ dị irè; N'aka nke ọzọ, site n'igbu oge nkwụsị nke gastric na ịba ụba satiety, ọ na-ebelata agụụ na iri nri, ma si otú a na-enweta njikwa ibu. Usoro ihe omume abụọ a na-enye GLP-2 uru pụrụ iche na ọgwụgwọ ụdị 2 metabolism na oke ibu, na-enye ndị ọrịa nhọrọ ọgwụgwọ zuru oke ..
Kedu ihe bụ usoro nke GLP-2?
GLP-2 na-ebelata glucose ọbara site na ọtụtụ usoro na-arụkọ ọrụ ọnụ, dị ka ndị a: ịgbalite onye na-anabata GLP-1: GLP-2 na-ejikọ ya na onye na-anabata GLP-1 na mkpụrụ ndụ beta pancreatic, na-eṅomi mmetụta nke GLP-1 eke. GLP-1 bụ homonụ nke emepụtara n'ime eriri afọ ma dị oke mkpa maka idowe glucose homeostasis 2. Ọ nwere ike ịkwalite njikọ insulin, mmepụta insulin, na mmetụta glucose, ma belata secretion glucagon iji kwalite satiety na igbochi agụụ 2.
Nrụ ọrụ a nwere ike ịkwalite mmepụta insulin. Insulin bụ isi homonụ na-ebelata glucose n'ọbara n'ime ahụ, nke nwere ike ịbawanye nnabata na ojiji nke glucose site na sel, si otú ahụ belata ọkwa glucose ọbara. N'ime ndị ọrịa nwere ụdị ọrịa metabolism nke 2, insulin ezughị oke ma ọ bụ na-ebelata mmetụta nke mkpụrụ ndụ na insulin, na-eduga n'ịbawanye glucose ọbara. GLP-2 na-abawanye mmepụta insulin site na ịgbalite GLP-1 nnabata, nke na-enyere aka melite njikwa glucose ọbara. N'otu oge ahụ, ịgbalite GLP-1 nnabata nwekwara ike igbochi ntọhapụ nke glucagon. Glucagon na-akwalitekarị glycogenolysis na gluconeogenesis na steeti ibu ọnụ, na-abawanye mmepụta glucose ọbara. Site na igbochi mmetụta glucagon, GLP-2 na-ebelata isi iyi nke glucose ọbara, nke na-enyere aka ịchịkwa glucose ọbara [2] (Anonymous, 2023).
Ntinye nke onye nnabata GIP: GLP-2 na-eme ihe na onye nnabata GIP n'otu oge. Mgbe arụ ọrụ ya gasịrị, ọ nwere ike ịkwalite mmetụta insulin na nzuzo. Onye na-anabata GIP na-anọkarị na anụ ahụ dịka mkpụrụ ndụ beta pancreatic. Mgbe ịgbalitechara ya, site na njikwa nke ụzọ mgbaàmà intracellular, secretion insulin na-abawanye, na nzaghachi nke mkpụrụ ndụ na insulin na-eme ka ọ dịkwuo mma, si otú a na-ebelata glucose ọbara n'ụzọ dị irè karị 2. GLP-2 bụ nke mbụ na klas dual glucagon-dị ka peptide-1 na glucose-adabere na glucose na-adabere na insulinotropic polypeptide (GIP) analogues nke ndị okenye na-akwado ụdị ọgwụgwọ insulin na-edozi ahụ. 2. GLP-2 bụ usoro kemịkalụ sịntetik dabere na usoro GIP, nke nwere peptide 39-amino acid mejupụtara. Ọ na-abawanye mmepụta insulin, na-ebelata ntọhapụ nke glucagon n'ụzọ dabere na glucose, na-ebelata ọnụ ọgụgụ glucose ọbara na-ebu ọnụ na postprandial, na-akwalite satiety, na-ebelata ibu, na-egbu oge ịpụpụ afọ.
Mmetụta agonist onye na-anabata ihe abụọ a na-eme GLP-2 dị irè karị n'ịkwalite mmepụta insulin na igbochi ntọhapụ glucagon karịa otu GLP-1 agonists [2]..
Na-egbu oge mkpofu gastric na ịba ụba satiety: GLP-2 nwere ike igbu oge ịwụfu afọ, gbatịa oge obibi nri n'ime afọ, na-ebelata ogo nnabata nke nri, wee zere mmụba dị ukwuu na glucose ọbara mgbe nri gasịrị. N'ihe ọmụmụ izizi na nke ụlọ ọgwụ, mmetụta GLP-2 na mkpofu afọ dị ka nke GLP-1 agonists. N'ime oke oke oke nri kpatara nri, ogo nke igbu oge afọ nke GLP-2 yiri nke GLP-1, mana mmetụta mgbochi ndị a na-apụ n'anya mgbe izu abụọ gachara ọgwụgwọ. N'ime ndị na-eso ya nwere ma na-enweghị ụdị 2 metabolism, GLP-2 otu ugboro kwa izu (≥5 na ≥4.5mg, n'otu n'otu) na-egbu oge mkpochapụ afọ mgbe otu ọgwụ gasịrị. N'ime ndị sonyere ahụike, a na-ebelata mmetụta a mgbe ọtụtụ doses nke GLP-2 ma ọ bụ dulaglutide [3] gasịrị. .
N'otu oge ahụ, ọ pụkwara ime ihe na usoro nhụjuanya nke etiti, na-abawanye satiety, na ibelata agụụ na nri oriri. Site n'ịchịkwa oriri, ọ na-enyere aka ịchịkwa ọkwa glucose ọbara n'ụzọ na-apụtaghị ìhè, karịsịa maka nsogbu oke ibu nke ndị ọrịa nwere ụdị 2 metabolism na-esonyere ya, ma na-enyere aka melite nguzogide insulin na ọnọdụ metabolic zuru oke [2]..
Imeziwanye mmetụta insulin na metabolism lipid: achọpụtara GLP-2 na-abawanye ọkwa adiponectin, nke bụ adipocytokine metụtara mmetụta insulin. Mmụba nke adiponectin na-enyere aka imeziwanye uche insulin, na-eme ka mkpụrụ ndụ na-enwe mmetụta nke insulin, wee si otú a na-ewelite ma jiri glucose mee ihe nke ọma, na-ebelata glucose ọbara [2]..
Na mgbakwunye, GLP-2 nwekwara ike melite profaịlụ lipid ma nwee mmetụta nchebe na ahụike obi. E gosiputara GLP-2 nwere ike imeziwanye ọbara mgbali elu, belata obere njupụta lipoprotein (LDL) cholesterol na triglycerides [4] .Nke a na-akwado uru ya zuru oke na njikwa glucose ọbara.

Ọtụtụ ọmụmụ ụlọ ọgwụ ekwenyela na mmetụta mbelata ibu dị ukwuu: N'ime nyocha nke aha ya bụ 'SURMOUNT-2', nnwale a bụ usoro nke 3, kpuru ìsì abụọ, nke enweghị usoro, ebe a na-achịkwa placebo na mba asaa. Ndị okenye (ndị dị afọ ≥18) nwere ọnụọgụ anụ ahụ (BMI) nke 27 kg / m² ma ọ bụ karịa na hemoglobin glycated (HbA₁c) nke 7-10% ka ekenye ya n'enweghị usoro ka ọ nata ntụtụ n'okpurucutaneous otu ugboro kwa izu nke GLP-2 (10mg ma ọ bụ 15mg) ma ọ bụ placebo maka izu 72. Nsonaazụ gosiri na n'izu 72, pasent nke ibu ibu na GLP-2 10mg na 15mg otu bụ -12.8% na -14.7%, n'otu n'otu, ebe na placebo otu bụ -3.2%.

Na mgbakwunye, ọtụtụ ndị ọrịa a na-emeso GLP-2 ruru n'ọnụ ụzọ mfu nke 5% ma ọ bụ karịa (79 - 83% vs 32%) [5] (Garvey WT, 2023). N'ime ọmụmụ 'SURMOUNT-2', nkezi ịdị arọ nke ntọala bụ 100.7 kg, BMI bụ 36.1 kg/m², na HbA₁c bụ 8.02%. Mgbe izu iri asaa na abụọ nke ọgwụgwọ gasịrị, GLP-2 abụghị naanị ibelata ibu ibu mana ọ rụkwara ọrụ dị mma na njikwa glucose ọbara [5]..
Mmetụta dị mma na neuropathy metụtara metabolism:
Ụfọdụ nnyocha egosiwo na glucagon-dị ka peptide 1 agonists (GLP1-RAs) nwere ike ibelata ihe ize ndụ nke ịda mbà n'obi na ndị ọrịa nwere ụdị 2 metabolism site na imeziwanye ebe nchekwa, mmụta, na imeri adịghị ike nghọta. Dị ka onye na-anabata insulin polypeptide receptor agonist abụọ (GIP-RA) / GLP-1RA, a mụrụ GLP-2 maka mmetụta ya na nrịbama nke uto neuronal (CREB na BDNF), apoptosis (BAX / Bcl2 ratio), ọdịiche (pAkt, MAP2, GAP43, na AGBL4), na nguzogide insulin (GLUT1, GLUT1, GLUT1, GLUT1 na GLUT1, GLUT1, GLUT1 na GLUT1, GLUT1, GLUT1, GLUT1 na GLUT1, GLUT1, GLUT1 na GLUT1, GLUT1, GLUT1 na GLUT1, GLUT1, GLUT1 na GLUT1, GLUT1, GLUT1, GLUT1 na GLUT1, GLUT1).

O gosikwara na GLP-2 nwere ike igbochi mmetụta ndị metụtara hyperglycemia na nguzogide insulin na ọkwa neuronal. Ya mere, GLP-2 nwere ike imeziwanye neurodegeneration nke hyperglycemia kpatara wee merie nguzogide insulin nke neuronal, na-enye nghọta ọhụrụ maka mmelite nke neuropathy metụtara metabolism [6]. .
Ọganihu nyocha na ọgwụgwọ ụdị 2 metabolism:
Ụfọdụ ọmụmụ egosila na GLP-2, dị ka ụdị ọgwụ hypoglycemic ọhụrụ, aghọwo onye mbụ GIP/GLP-1R agonist kwadoro maka ọgwụgwọ nke metabolism na United States.
