specialized proteins that bind specific molecules to trigger cellular responses

Receptors are specialized protein molecules found on the surface of cells or within cells that bind to specific substances, such as hormones, neurotransmitters, or drugs. When these substances attach to the receptors, they trigger a response within the cell, influencing various physiological processes. For example, in the context of hair biology, androgen receptors on hair follicle cells can bind to hormones like testosterone, affecting hair growth and potentially contributing to conditions like androgenetic alopecia (pattern baldness).
