  2. Autocrine signaling - Wikipedia

    en.wikipedia.org/wiki/Autocrine_signaling

    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.

  3. Cell signaling - Wikipedia

    en.wikipedia.org/wiki/Cell_signaling

    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.

  5. Chemical messenger - Wikipedia

    en.wikipedia.org/wiki/Chemical_messenger

    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 ...

  7. Cytokine - Wikipedia

    en.wikipedia.org/wiki/Cytokine

    In contrast, classic hormones, such as insulin, are secreted from discrete glands such as the pancreas. [13] The current terminology refers to cytokines as immunomodulating agents . A contributing factor to the difficulty of distinguishing cytokines from hormones is that some immunomodulating effects of cytokines are systemic ( i.e. , affecting ...

  8. Neurohormone - Wikipedia

    en.wikipedia.org/wiki/Neurohormone

    A neurohormone is any hormone produced and released by neuroendocrine cells (also called neurosecretory cells) into the blood. [1] [2] By definition of being hormones, they are secreted into the circulation for systemic effect, but they can also have a role of neurotransmitter or other roles such as autocrine (self) or paracrine (local) messenger.

  9. Sympathoadrenal system - Wikipedia

    en.wikipedia.org/wiki/Sympathoadrenal_system

    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 ...
