рецептор ; рецепторное нервное окончание
- The solid outline encloses the area within which we measured each individual receptor.
- But the answer to this riddle is that they have a receptor, most probably in the brain, that enables light detection to bypass normal, ocular channels.
- It appeared that these substances not only stimulated the adrenaline receptor but remained attached to it and blocked it.
- In vertebrates, the division of the spinal cord recalls the original segmentation, and the organization of the nervous system is still largely based on a segmental arrangement of both receptor and effector nerves.
- Finally, the catalytic subunit of PKA can directly increase AMPA receptor function.
- As shown in Fig. 3a, thymuses of TCR - mutant mice are largely devoid of CD4 or CD8 SP cells but retain normal numbers of small DP cells without the interleukin-2 (IL-2) receptor (IL-2R - DP cells) (Fig. 2b).
- This state of affairs causes no surprise when it is recognised that "what is understood is at least as dependent on how the receptor perceives the message as on how the communicator presents it" (Kraft 1979:148).
- These separate receptor mechanisms are coupled to energy-requiring (GTP or ATP) transducing mechanisms which activate phospholipase C (PLC) to hydrolyse the lipid precursor phosphatidylinositol 4,5-bisphosphate (PtdIns(4,5)P 2 ) to give both DAG and InsP 3 .
- Potentiation of a similar duration can be produced by decreasing the number of stimuli in the tetanus or by other manoeuvres which reduce the level of NMDA receptor activation.
- Detailed biochemical work has shown that target cells carry an insulin receptor molecule on their surfaces, which reacts with insulin molecules in the surrounding body fluids.
- At the same time the Holy Spirit was at work on the receptor's end of the communication process (1 Thess. 1:6; Col. 1:9).
- In both cases it seems that the problem lay in the transmission of the activation signal across the target cell membrane, once insulin has bound to the surface receptor.
- The oddest thing about X is that like naloxone, it blocks the opiate receptor; this is opposite from morphine and the enkephalins.
