Cell Communication

Endocrine Signaling

Long-distance cell communication that involves the release of hormones into the bloodstream

Paracrine Signaling

Short-distance cell communication that involves electrochemical signals in the nervous system that use neurotransmitter to talk to neighboring cells

Autocrine Signaling

Self cell communication that involves a cell releasing a signaling molecule that binds to receptors on its own surface, allowing the cell to self-regulate

What is endocrine signaling used for?

signals from the pituitary gland (brain) release hormones into the bloodstream that then regulate growth, metabolism, and homeostasis

What is paracrine signaling used for?

cells across the body release signals that regulate nearby activities such as tissue repair and development and creating an immune responses by recruiting immune cells to a site

What is autocrine signaling used for?

cells send signals to regulate their own growth, immune response, and cellular differentiation, influencing both individual cell behavior and tissue function. However, this can contribute to cancer progression
