Hauv autocrine cov txheej txheem taw qhia, molecules ua rau tib lub hlwb uas tsim lawv. Hauv kev taw qhia paracrine, lawv ua rau cov hlwb nyob ze. Autocrine Cov teeb liab muaj xws li extracellular matrix molecules thiab ntau yam uas txhawb kev loj hlob ntawm tes.
Tom qab ntawd, autocrine ua haujlwm li cas?
Autocrine teeb liab yog tsim los ntawm signaling hlwb uas ua tau kuj khi rau lub ligand ntawd yog tso tawm. Qhov no txhais tau tias lub signaling cell thiab lub hom phiaj cell ua tau ua tib yam lossis zoo ib yam ntawm tes (lub prefix auto- txhais tau tias nws tus kheej, ceeb toom tias lub xov tooj ntawm tes xa cov teeb liab rau nws tus kheej).
Tsis tas li ntawd, qhov txawv ntawm autocrine thiab paracrine yog dab tsi? Autocrine : hom tshuaj hormones uas cov tshuaj hormons khi rau receptors rau ntawm lub cell thiab cuam tshuam rau lub cell uas tsim nws. Paracrine : piav qhia txog kev ua haujlwm ntawm cov tshuaj hormones uas cov tshuaj hormones tawm ntawm cov hlwb thiab khi rau receptor ntawm cov hlwb nyob ze thiab cuam tshuam rau lawv txoj haujlwm.
Ntawm no, lub luag haujlwm ntawm autocrine signaling yog dab tsi?
Autocrine signaling yog ib hom cell teeb liab nyob rau hauv uas ib tug cell secretes ib cov tshuaj hormones los yog chemical messenger (hu ua autocrine agent) uas khi rau autocrine receptors ntawm tib lub cell, ua rau kev hloov hauv lub cell.
Puas yog autocrine intercellular?
Autocrine signaling txhais tau tias kev tsim khoom thiab tso tawm ntawm ib qho extracellular mediator los ntawm ib lub xovtooj tom qab los ntawm kev khi ntawm tus neeg kho kom haum xeeb rau receptors ntawm tib lub xovtooj los pib lub teeb liab hloov. Ib daim ntawv zoo tus yam ntxwv ntawm autocrine Kev taw qhia yog qhov tso tawm ntawm IL-1 los ntawm macrophages.
