Muaj plaub pawg ntawm tshuaj Kev taw qhia pom muaj nyob rau hauv ntau cov kab mob: paracrine signaling, endocrine signaling, autocrine signaling, thiab ncaj qha signaling hla qhov sib txawv junctions.

Tsuas yog li ntawd, 4 hom kev taw qhia ntawm tes yog dab tsi?

Muaj plaub yam yooj yim ntawm cov tshuaj teeb liab pom muaj nyob rau hauv multicellular kab mob: paracrine teeb liab , autocrine ua teeb liab , kab mob endocrine teeb liab , thiab teeb liab los ntawm kev sib cuag ncaj qha.

Tom qab, lo lus nug yog, dab tsi yog receptors thiab nws hom? Receptors yog protein molecules nyob rau hauv lub hom phiaj cell los yog nyob rau nws nto uas khi ligands. Muaj ob hom ntawm cov receptors : sab hauv cov receptors thiab cell-nto cov receptors.

Dab tsi yog qhov taw qhia molecule?

Teeb liab molecules yog cov molecules uas yog lub luag haujlwm rau kev xa cov ntaub ntawv ntawm cov hlwb hauv koj lub cev. Qhov loj, zoo li, thiab kev ua haujlwm ntawm ntau hom signaling molecules tuaj yeem sib txawv heev. Qee tus nqa cov teeb liab hla luv luv, thaum lwm tus xa cov ntaub ntawv hla qhov deb heev.

Hom kev taw qhia molecule yog epinephrine?

Thaum twg epinephrine khi rau nws cov receptor ntawm cov leeg nqaij (a hom ntawm G protein-coupled receptor), nws ua rau a teeb liab transduction cascade cuam tshuam nrog kev tsim cov tub txib thib ob molecule cyclic AMP (cAMP).
