Juxtacrine
Cardiac muscle cells communicate through connexions, forming gap junctions for coordinated contraction
Juxtacrine
Notch proteins on one cell bind to Delta proteins on an adjacent cell influencing cell fate decisions
Juxtacrine
Antigen-presenting cells display foreign peptides on their surface to activate T cells through direct contact
Juxtacrine
Cells in the intestinal lining communicate via gap junctions, allowing small molecules to pass directly between them
Juxtacrine
A cell releases growth factors that bind to its own surface receptors, stimulating cell division
Juxtacrine
Epidermal growth factor (EGF) binds to receptors on the same cell that produced it, promoting cell survival
Juxtacrine
A neuron releases neurotransmitters that bind to receptors on an adjacent neuron in a synapse
Paracrine
Nitric oxide produced by Endothelial cells diffuses to nearby smooth muscle cells in blood vessels
Paracrine
Serotonin released by enterochromaffin cells in the gut acts on the same cells to regulate their function
Paracrine
Platelets release growth factors that stimulate nearby cells to promote wound healing
Paracrine
Prostaglandins released by damaged cells act on nearby sensory neurons to induce pain sensation
Paracrine
A white blood cells releases cytokines that affect nearby immune cells in inflamed tissue
Endocrine
Glucagon released from pancreatic alpha cells travels through the bloodstream to target liver cells
Endocrine
Thyroid hormones travel through the bloodstream to affect metabolism in various body tissues
Endocrine
Estrogen hormones released from ovaries travel through the bloodstream to affect breast tissue and uterus
Endocrine
Insulin released from pancreatic beta cells travels through the bloodstream to affect liver and muscle cells
Endocrine
Growth hormone released from the pituitary gland travels through the bloodstream to stimulate growth in various tissues
Endocrine
Cortisol released from the adrenal glands travels through the bloodstream to affect multiple body systems
