Unveiling the Sensory Power of Hair Follicles

Researchers at Imperial College London have discovered a previously unknown mechanism within hair follicles that allows us to detect touch. Hair follicle cells, in addition to nerve endings in the skin, can sense touch and release neurotransmitters histamine and serotonin in response. This finding may provide insights into the role of histamine in inflammatory skin conditions like eczema. The study was conducted using cell cultures and further research is needed to confirm the findings in living organisms.
