Autocrine signaling is a form of cell signaling in which a cell secretes a hormone or chemical messenger (called the autocrine agent) that binds to autocrine receptors on that same cell, leading to changes in the cell. [1] This can be contrasted with paracrine signaling, intracrine signaling, or classical endocrine signaling.
Autocrine signaling occurs when the chemical signal acts on the same cell that produced the signaling chemical. [1] Intracrine signaling occurs when the chemical signal produced by a cell acts on receptors located in the cytoplasm or nucleus of the same cell. [2] Juxtacrine signaling occurs between physically adjacent cells. [3]

A chemical message is any compound that serves to transmit a message, and may refer to: Hormone, long range chemical messenger; Neurotransmitter, communicates to adjacent cells; Neuropeptide, a protein sequence which acts as a hormone or neurotransmitter. The blood or other body fluids transport neuropeptides to non adjacent target cells, where ...
Cytokines (/ ˈ s aɪ t ə k aɪ n /) [1] are a broad and loose category of small proteins (~5–25 kDa [2]) important in cell signaling. Due to their size, cytokines cannot cross the lipid bilayer of cells to enter the cytoplasm and therefore typically exert their functions by interacting with specific cytokine receptors on the target cell ...
The two main chemical messengers of the sympathoadrenal system are norepinephrine and epinephrine (also called noradrenaline and adrenaline respectively). These chemicals are created by the adrenal glands after receiving neuronal signals from the sympathetic nervous system. The different physiological effects of these chemicals depend on the ...
SP initiates expression of almost all known immunological chemical messengers . [20] [21] [22] Also, most of the cytokines, in turn, induce SP and the NK1 receptor. [23] [24] SP is particularly excitatory to cell growth and multiplication, [25] via usual, [26] as well as oncogenic drivers. [27] SP is a trigger for nausea and emesis. [28]
Neuropeptide Y. Neuropeptides are chemical messengers made up of small chains of amino acids that are synthesized and released by neurons.Neuropeptides typically bind to G protein-coupled receptors (GPCRs) to modulate neural activity and other tissues like the gut, muscles, and heart.
