Txhua xyoo, Ntiaj Teb Lub Raum Hnub yog qhov tseem ceeb ceeb toom ntawm lub ntiaj teb qhov tseem ceeb ntawm lub raum noj qab haus huv. Lub hom phiaj kev noj qab haus huv thoob ntiaj teb no yog txhawm rau ua kom muaj kev paub txog pej xeemkab mob raum, txhawb kev tiv thaiv, kev kuaj mob ntxov, thiab kev kho mob zoo, yog li txo qhov cuam tshuam loj ntawm lub raum tsis zoo rau tib neeg kev noj qab haus huv. Ntawm cov kab mob ntawm lub raum, cov kab mob autoimmune raum (AIKD) muaj kev txhawj xeeb tshwj xeeb vim lawv cov kab mob nyuaj thiab qhov tshwm sim loj heev, sawv ua tus pab cuam loj raumob raum mob (CKD)thiab xaus - kab mob raum (ESRD). Txawm hais tias muaj kev vam meej hauv AIKD cov tswv yim kho mob, qhov nyuaj etiological thiab ntau yam kev kho mob tshwm sim ua rau muaj teeb meem tsis tu ncua. Yog li ntawd, kev txhim kho cov kev kho tshiab tshiab rau AIKD, tshwj xeeb tshaj yog rau nws cov kab mob sawv cev,Membranous Nephropathy (MN), yog qhov tseem ceeb ntawm kev kho mob tseem ceeb thiab ceev ceev. Tsiaj cov qauv txuas qhov sib txawv ntawm cov kev tshawb fawb hauv paus thiab kev siv tshuaj kho mob, ua cov cuab yeej tseem ceeb rau delve rau hauv pathogenesis ntawm AIKD thiab ntsuas qhov ua tau zoo thiab kev nyab xeeb ntawm cov tshuaj tshiab.
Pathphysiology ntawm Membranous Nephropathy (MN) thiab Kev Tshawb Fawb Kev Sib Tw
Membranous Nephropathy (MN) yog ib hom kab mob autoimmune raum uas tshwm sim los ntawm kev ua kom lub cev tsis muaj zog, ua rau kev tsim cov autoantibodies tawm tsam hauv lub raum antigens. Cov tshuaj tiv thaiv no tsim cov tshuaj tiv thaiv kab mob nyob rau sab nrauv ntawm glomerular hauv qab daus daim nyias nyias (GBM), thaum kawg ua rau glomerular pom muaj nuj nqi. Hauv thawj MN, podocyte antigen phospholipase A2 receptor (PLA2R) yog lub hom phiaj tseem ceeb antigen. Lub pathogenesis ntawm MN yog intricate, nrog rau oxidative kev nyuaj siab, inflammatory teb, tiv thaiv cell activation, thiab ntxiv system kev koom tes. Antigen-ntaus hlwb (APCs) paub thiab nthuav tawm cov tshuaj tiv thaiv podocyte, xws li PLA2R, ua kom T cell thiab B hlwb. B hlwb sib txawv rau hauv cov ntshav plasma, tsim los tiv thaiv -PLA2R cov tshuaj tiv thaiv. Cov tshuaj tiv thaiv no khi rau PLA2R ntawm podocytes, tsim cov kab mob tiv thaiv kab mob uas tso rau hauv qab GBM, ua kom lub zog ntxiv thiab ua rau cov podocytes puas tsuaj. Qhov no cascade ntawm pathological txheej xwm thaum kawg nce glomerular filtration membrane permeability, ua rau cov proteinuria loj heev, thiab muaj peev xwm mus rau GBM thickening, podocyte ko taw txheej txheem effacement, thiab glomerulosclerosis, culminating nyob rau hauv mob raum raug mob thiab kab mob kev loj hlob.
Kev tsim tshuaj yeeb rau MN ntsib teeb meem ntau heev. Ua ntej, txoj kev pathophysiology nyuaj thiab ntau lub hom phiaj kho mob yuav tsum muaj cov qauv zoo dua uas ua raws li qhov pib thiab kev loj hlob ntawm tib neeg cov kab mob. Qhov thib ob, cov qauv tsiaj preclinical yuav tsum tau kwv yees siv tshuaj zoo thiab kev nyab xeeb rau tib neeg. Yog li ntawd, txoj kev loj hlob ntawm cov qauv tsiaj uas ze recapitulate cov yam ntxwv ntawm tib neeg MN yog ib qho tseem ceeb rau accelerating the innovation of MN therapeutics.
Prisys Biotech's Cynomolgus Monkey Membranous Nephropathy Model: Kev tsim kho thiab kev zoo
Txhawm rau daws cov teeb meem hauv kev tsim tshuaj Membranous Nephropathy, Prisys Biotechnologies (Prisys Biotech), siv nws cov kev paub dhau los hauvtsis yog-neeg primate (NHP) qauvkev loj hlob, tau tsim covAnti-tib neeg PLA2R Antibody-Induced Cynomolgus Monkey Membranous Nephropathy (MN) Model. Cov qauv no siv cov tshuaj tiv thaiv exogenous -tib neeg PLA2R cov tshuaj tiv thaiv kab mob los ua kom muaj zog MN hauv cynomolgus liab, ncaj ncees rov hais dua cov kab mob thiab kab mob ntawm tib neeg thawj MN.
Prisys Biotech's MN cynomolgus liab qauv muaj cov txiaj ntsig zoo hauv kev sim tsim:
