Cov receptors no tau nyob hauv thaj chaw zoo heev rau presynaptic cheeb tsam (hauv hippocampus), qhov uas lawv hloov pauv cov tshuaj neurotransmitters xws li glutamate, acetylcholine, GABA thiab noradrenaline [32–35].
Adenosine receptor nyob qhov twg?
Adenosine A2A receptor yog tam sim no nyob rau hauv lub hlwb, lub plawv, ntsws, thiab spleen The adenosine A2B receptor muaj nws qhov loj ntawm txoj hnyuv loj thiab zais zis, thiab adenosine A3 receptor muaj nyob rau hauv lub ntsws, siab, hlwb, testis, thiab plawv.
Dab tsi yog adenosine receptors hauv lub hlwb?
Adenosine yog nruab nrab paj hlwb neuromodulatoruas muaj cov receptors tshwj xeeb. Thaum adenosine khi rau nws cov receptors, neural kev ua haujlwm qeeb, thiab koj tsaug zog. Adenosine yog li pab txhawb kev pw tsaug zog thiab nthuav cov hlab ntsha, tej zaum yuav ua kom muaj oxygenation zoo thaum pw tsaug zog.
A1 thiab a2a receptors nyob qhov twg?
Hauv lub hlwb, A1, A2B, thiab A3 receptors muaj kev faib tawm thoob plaws, txawm hais tias A2B thiab A3 receptors muaj qib qis. Txawm li cas los xij, A2ARs feem ntau nyob hauv cheeb tsam lub striatum, olfactory tubercle, thiab cov nucleus accumbens [3].
Lub luag haujlwm ntawm adenosine receptor yog dab tsi?
Tus adenosine receptors tswj cov adenylate cyclase indirectly los ntawm activating guanine nucleotide regulatory proteins (G proteins). G proteins sawv cev rau tsev neeg uas muaj kev sib txuas ntawm cov proteins.
