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.
Interferon-alpha, an interferon type I, was identified in 1957 as a protein that interfered with viral replication. [5] The activity of interferon-gamma (the sole member of the interferon type II class) was described in 1965; this was the first identified lymphocyte-derived mediator. [6]

Autocrine signaling involves a cell secreting a hormone or chemical messenger (called the autocrine agent) that binds to autocrine receptors on that same cell, leading to changes in the cell itself. [13] This can be contrasted with paracrine signaling, intracrine signaling, or classical endocrine signaling.
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 ...
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 ...
The endocrine system is a control system of ductless endocrine glands that secrete chemical messengers called hormones that circulate within the body via the bloodstream to affect distant organs. It does not include exocrine glands such as salivary glands , sweat glands and glands within the gastrointestinal tract .
Endocrine component: Heterocrine glands produce hormones, which are chemical messengers that travel through the bloodstream to target organs or tissues. These hormones play a vital role in regulating numerous physiological processes, such as metabolism, growth, and the immune response.
