Tsis yog- Tib neeg Primate Models Of Pulmonary Fibrosis: Advancing Translational Accuracy in Respiratory Drug Development

Kev txhim kho cov kev kho mob zoo rau cov kab mob ntsws interstitial (ILDs), tshwj xeebIdiopathic Pulmonary Fibrosis (IPF), tseem yog ib qho teeb meem tseem ceeb tshaj plaws hauv cov tshuaj ua pa. Txawm hais tias kev tshawb fawb ua ntej siv cov qauv nas, kev txhais lus ntawm cov chaw tshiab molecular rau hauv cov txiaj ntsig kev kho mob tau zoo tau muaj keeb kwm tsis zoo, feem ntau yog vim tsis ua tiav ntawm cov qauv ib txwm ua kom rov ua dua qhov nyuaj, tsis yog - daws cov txheej txheem fibroproliferative pom hauv tib neeg cov neeg mob.

Tsis yog-tib neeg primate (NHP) qauvtau tshwm sim los ua tus choj tseem ceeb hauv qhov kev txhais lus sib txawv no. Los ntawm kev muab lub platform uas ze ze tsom iav tib neeg pulmonary anatomy, lub cev tiv thaiv kab mob, thiab kev loj hlob ntawm fibrotic, NHP qauv - koom ua ke nrog kev soj ntsuam xyuas qib siab thiab kev soj ntsuam ntev ntev - muab qhov kev kwv yees ntau dua rau kev soj ntsuam cov neeg sib tw antifibrotic thiab cov tshuab xa tawm tshiab.

Pulmonary fibrosis yog tus cwj pwm los ntawm kev hloov pauv ntawm kev noj qab haus huv ntawm lub ntsws parenchyma nrog extracellular matrix (ECM) cov proteins, ua rau muaj kev cuam tshuam ntawm kev tsim vaj tsev thiab irreversible poob ntawm kev sib pauv roj. Thaum cov qauv nas (feem ntau yog bleomycin-induced) tau ua qhov tseem ceeb hauv kev txheeb xyuas TGF- -txoj kev sib kho, lawv feem ntau pom muaj "rov qab" fibrotic profile uas tsis ua raws li kev mob ntev, tus kheej -txheej xwm ntawm tib neeg ILDs.

Hauv kev tsim tshuaj, qhov tsis muaj tib neeg -zoo li kev ua pa ntawm lub cev hauv cov tsiaj me feem ntau ua rau muaj kev suav tsis raug txog kev siv tshuaj biodistribution, lub hom phiaj kev koom tes, thiab kev siv tshuaj. NHPs, tshwj xeeb tshaj yog cynomolgus thiab rhesus macaques, qhia cov noob caj noob ces siab thiab lub cev nqaij daim tawv nrog tib neeg, ua rau lawv tus qauv kub rau kev ntsuas kev nyab xeeb thiab kev ua tau zoo ntawm tom ntej - tiam biologics, siRNA, thiab cell- raws li kev kho mob.

Induction Methodology

Qhov tsim nyog tshaj plawsNHP qauv rau pulmonary fibrosissiv lub hom phiaj instillation ntawm bleomycin los yog lwm yam fibrogenic agents rau hauv tej lub ntsws lobes. Tsis zoo li kev tswj hwm kev tswj hwm, hauv zos instillation ntawm bronchoscopy tso cai rau:

• Intra- Tsiaj Controls:Siv tsis yog -cov lobes instilled ua cov hauv paus hauv paus.

• Regional Specification:Tsom ntsoov rau cov lus teb fibrotic kom tso cai rau siab dua - kev daws teeb meem duab thiab cov ntaub so ntswg sampling.

Technical Execution: Bronchoscopy thiab Xa

Lub tshuab ua pa ntawm Prisys siv cov chaw kho mob -qib bronchoscopy rau kev xa tshuaj thiab kev kuaj. Qhov no suav nrog:

• Targeted Instillation:Kev tswj hwm ncaj qha ntawm cov neeg ua haujlwm fibrogenic rau hauv segmental lossis sub-segmental bronchi.

• Intracheal Aerosol Delivery:Kev siv Aerogen® vibrating mesh nebulizers rau tag nrho - lub ntsws los yog lub hom phiaj ntawm txoj kev ua pa, simulating tib neeg kev nqus pa.

• Bronchoalveolar Lavage (BAL):Longitudinal sau ntawm BAL kua (BALF) los soj ntsuam inflammatory cell infiltration (neutrophils, macrophages) thiab cytokine profiles (IL-6, TGF- ).

Cov kev txwv ntawm cov qauv nas hauv kev tshawb fawb fibrosis yog cov hauv paus hauv kev sib txawv ntawm cov kab mob lom neeg:

• Kev daws teeb meem vs. Progression:Cov qauv nas bleomycin feem ntau qhia qhov kev daws teeb meem tseem ceeb tom qab 28 hnub. Tib neeg fibrosis yog kev loj hlob; NHP cov qauv tuaj yeem ua kom pom cov kev hloov pauv tsis tu ncua ntev dua 3-6 lub hlis, muab lub qhov rais rau kev ntsuas kev saib xyuas ntawm cov nyhuv kho.

• Anatomical Nplai:Kev nthuav dav dav ntawm NHP txoj hlab pa thiab muaj cov pa bronchioles (feem ntau tsis muaj nyob hauv nas) yog qhov tseem ceeb rau kev ntsuas qhov tso tawm ntawm cov tshuaj inhaled.

• Immune Homology:NHPs qhia cov hom phiaj tshuaj zoo ib yam thiab cov neeg tiv thaiv kab mob zoo sib xws (piv txwv li, cov txheej txheem macrophage tshwj xeeb) koom nrog hauv fibrotic cascade, uas yog qhov tseem ceeb rau kev sim tshuaj monoclonal antibodies thiab immunomodulators.

• Muaj peev xwm ua duab:Cov duab nas lub ntsws tsis muaj qhov kev daws teeb meem los ntsuas qhov hloov maj mam hloov hauv qhov sib txawv ntawm qhov tuab. NHPs tau sib haum nrog kev kho mob siab -Kev daws teeb meem Computed Tomography (HRCT) thiab PET-CT raws tu qauv.

Physiological txheeb ze

NHPs nthuav tawm tib neeg -zoo li tus pa ua pa, lub ntsws ntim, thiab lub diaphragm muaj nuj nqi. Qhov no tso cai rau kev ntsuas ntawm qhov chaw kho mob- qhov kawg qhov sib npaug, xws li pulmonary resistance thiab kev ua raws, siv cov tshuab xws li FlexiVent lossis tshwj xeeb NHP- lub ntsej muag hloov kho thaum lub sij hawm nebulization.

Longitudinal Monitoring thiab Biomarkers

Kev muaj peev xwm ua tau rov ua piv txwv thiab kev ntsuas hauv tib yam kev kawm ua rau txo qis cov suab nrov thiab muab kev pom dav dav ntawm kev kis kab mob:

• Circulating Biomarkers:Kev soj ntsuam ntawm Pro-collagen I, CA125, thiab Fibroblast Activation Protein (FAP) hauv cov ntshav.

• BALF Kev Ntsuam Xyuas:Tiag -lub sij hawm ntsuam xyuas ntawm microenvironment hauv zos.

• Lub cev Biopsy:Ultrasound los yog CT- coj lub ntsws punctures rau histopathological validation ntawm fibrosis qib (Ashcroft scoring sib npaug).

Prisys Biotechnologies tau tsim muaj ntau txoj kev qhuab qhia uas sib koom ua ke hauv kev kho mob -qib duab nrog AI- tsav kom muaj nuj nqis los txhim kho tus nqi kwv yees ntawm NHP kev tshawb fawb fibrosis.

Quantitative CT Analysis

Siv Amira Software thiab tshwj xeeb analytical sequences (piv txwv li, 1.0 x 0.8 ntsws HRCT), Prisys enables kev hloov pauv ntawm CT scans rau hauv cov ntaub ntawv ntau.

• Automated Segmentation:Precise anatomical segmentation ntawm lub ntsws lobes kom muaj nuj nqis hloov pauv thiab cov ntaub so ntswg ceev.

• Fibrosis Hloov %:Xam cov feem pua ​​​​ntawm fibrotic ntim txheeb ze rau lub hauv paus los yog tswj lobes (xws li, daim ntawv qhia kev loj hlob ntawm Hnub 56 txog Hnub 98).

• Radiotracer Uptake:Kev koom ua ke nrog PET-CT los ntsuas kev ua haujlwm hauv metabolic lossis lub hom phiaj kev koom tes (siv 18F-FDG lossis tshwj xeeb fibroblast-cov phiaj xwm taug qab).

Respiratory Research Infrastructure

• AAALAC-Kev lees paub Vivarium:Ua kom ntseeg tau cov qauv siab tshaj plaws ntawm kev noj qab haus huv tsiaj, uas yog qhov tseem ceeb rau kev ruaj ntseg ntawm cov qauv kab mob.

• BSL-2 Muaj peev xwm:Tso cai rau kev kawm ntawm fibrosis nyob rau hauv cov ntsiab lus ntawm kab mob los yog kab mob exacerbations (xws li, post-viral pulmonary sequelae).

• Specialized Veterinary Teams:Cov kws tshaj lij hauv kev cuam tshuam kev phais mob, suav nrog kev phais mob ntsws thiab mob ntsws ntev rau kev soj ntsuam PK / PD.

Lub NHP Pulmonary Fibrosis platform txhawb nqa ntau theem ntawm kev txhim kho tshuaj:

• Kev ntsuas kev ua tau zoo:Longitudinal kuaj ntawm antifibrotics (xws li, Nintedanib validation) los soj ntsuam txo cov fibrotic ntim thiab txhim kho hauv lub ntsws ua haujlwm.

• Inhaled Drug Delivery:Characterizing lub pharmacokinetics (PK) ntawm nebulized me me molecules los yog biologics nyob rau hauv lub ntsws cov ntaub so ntswg vs. systemic ncig.

• Lub Hom Phiaj Kev Koom Tes (TE):Siv cov duab molecular imaging (PET) los yog biopsy-raws li lub hom phiaj nyob rau hauv kev soj ntsuam xyuas kom paub meej tias cov tshuaj tau ncav cuag thiab khi rau nws qhov chaw npaj (xws li, TG2 kev ua haujlwm hauv lub raum / pulmonary fibrosis).

• IND-Kev Pab Txhawb:Muab siab -cov ntaub ntawv ncaj ncees ntawm kev nyab xeeb thiab kev ua tau zoo nyob rau hauv ib hom tshuaj muaj feem xyuam rau kev txhawb nqa kev tswj xyuas.

Lub neej yav tom ntej ntawm NHP-raws li kev tshawb fawb txog kev ua pa yog nyob rau hauv kev sib koom ua ke ntawm AI thiab multi-modal biomarkers.AI-raws li kev txheeb xyuas tus cwj pwm(xws li Prisys BehaviorAtlas®) tau hloov kho kom pom cov kev hloov pauv hloov maj mam hauv kev ua si lossis "sab ntsuj plig" uas cuam tshuam nrog kev ua pa nyuaj, muab lub hom phiaj ntsuas kev ua tau zoo- ntawm- kev txhim kho lub neej. Tsis tas li ntawd, kev sib koom ua ke ntawmnasal{0}}rau- hlwb(N2B) thiab lwm txoj hauv kev xa tawm tshiab tso cai rau kev tshawb nrhiav qhov cuam tshuam ntawm kev kho ua pa ntawm CNS thiab lwm yam hauv nruab nrog cev, ua kom muaj kev nkag siab zoo ntawm lub qhov rais kho.
