    GlossaryCell Signaling (Signal Transduction)

    cells communicate through molecular signals to coordinate functions

    Cell signaling, also known as cell communication or signal transduction, is the process by which cells detect and respond to external signals through a series of molecular events. These signals can come from other cells, the environment, or within the cell itself, and they often involve the activation of specific receptors and subsequent pathways that lead to a cellular response, such as growth, division, or apoptosis. This process is crucial for maintaining homeostasis and coordinating complex biological functions.

      Hair loss in Androgenetic alopecia (AGA) is due to altered cell sensitivity to hormones, not increased hormone levels. Hair growth periods shorten over time, causing hair to become thinner and shorter. This is linked to miscommunication between cell pathways in hair follicles. There's also a change in gene expression related to blood vessels and cell growth in balding hair follicles. The exact molecular causes of AGA are still unclear.
