Yes, cells can alter their number of receptors in response to various stimuli, a process known as receptor plasticity. This can involve upregulation, where more receptors are produced in response to low levels of a ligand, or downregulation, where receptor numbers decrease in response to high ligand concentrations. Such adjustments allow cells to maintain homeostasis and adapt to changing environmental conditions. This dynamic regulation is crucial for processes like neurotransmission, hormone signaling, and immune responses.
What else can I help you with?
Are surface protein receptors protein?
Yes, surface receptors are made of protein units in cells.
Cells called what detect changes in the environment known as stimuli?
Sensory receptors detect changes in the environment known as stimuli. These receptors are specialized cells that send signals to the brain or spinal cord in response to specific types of stimuli such as light, sound, pressure, or chemical signals.
Do egg cells have chemicals on the tip of the head?
Egg cells have receptors on their surface that can bind to chemicals like sperm. These receptors help facilitate the process of fertilization by allowing the sperm to attach to the egg cell.
What are the structures that allow hormones to bind to their target cells?
Hormones bind to specific protein receptors on the surface or inside target cells. These receptors are typically found on the cell membrane or in the cytoplasm. Once the hormone binds to its receptor, it triggers a signaling cascade that leads to specific cellular responses.
The hearing receptors of the orgen of corti are called?
The hearing receptors of the organ of Corti are called hair cells. These specialized cells are responsible for converting sound vibrations into electrical signals that can be interpreted by the brain. Hair cells play a crucial role in our ability to detect and process sound.
Do fat cells have pain receptors?
Yes, fat cells do not have pain receptors.
What are the receptors in the eye?
You have rod cells and cone cells as receptors in your eye. Rods are for intensity of the light. Cone cells are for color vision.
Factors controlling secretion of the stomach?
The parietal cell in the stomach secrets gastric acid, which is hydrochloric acid (HCl). The Secretion of HCl by the parietal cell is stimulated by receptors for acetylcholine (muscarinic), histamine, and gastrin. The enterochromaffin cells (ECL) also have gastrin receptors and muscarinic receptors. ECL cells release histamine which reacts with H2 receptors (histamine 2 receptors) on parietal cells. Somatostatin is released by delta cells and decreases histamine release by ECL cells.
Are cells without receptors affected by hormones?
no they are not
Are surface protein receptors protein?
Yes, surface receptors are made of protein units in cells.
What type of cells contain cd4 receptors?
CD4 receptors are primarily found on a subset of T cells known as CD4+ T helper cells. These cells play a crucial role in the immune response by assisting other immune cells, such as B cells and cytotoxic T cells. CD4 receptors are also present on some macrophages and dendritic cells, but their primary association is with CD4+ T lymphocytes.
Cells called what detect changes in the environment known as stimuli?
Sensory receptors detect changes in the environment known as stimuli. These receptors are specialized cells that send signals to the brain or spinal cord in response to specific types of stimuli such as light, sound, pressure, or chemical signals.
What are your serotonin receptors?
5-HT receptors are the receptors for serotonin. They are located on the cell membrane of nerve cells and other cell types in animals.
Does up-regulation involve the loss of receptors and prevents the target cells from overreacting to persistently high hormone levels?
No, up-regulation involves an increase in the number of receptors on target cells in response to low hormone levels, which enhances the cell's sensitivity to the hormone. This helps the target cells respond more effectively to the hormone.
The reason only certain cells are affected is that the membranes of these cells have specific?
receptors
What receptors provide the sense of hearing?
Hair cells
What is receptors in Nervous System?
specialized sensory cells
