TRPV1 Sensory Nerves May Be Key to the Genesis of Airway Hyperreactivity in Experimental Asthma

TRPV1 Sensory Nerves May Be Key to the Genesis of Airway Hyperreactivity in Experimental Asthma

A new study in the Proceedings of the National Academy of Sciences (PNAS) of the USA implicates the transient receptor potential vanilloid 1 (TRPV1)-expressing sensory nerves in the pathogenesis of asthma and/or asthma attacks. The TRPV1 receptor, initially identified as the receptor for capsaicin, the hot component of chilli peppers, is typically expressed in sensory […]

Rejecting Allergens: The Avoidance Behavior

Rejecting Allergens: The Avoidance Behavior

Evolving Concepts The immune system can recognize, assimilate or reject self and non-self components. Indeed, immunological activities vary in a spectrum that goes from total tolerance (assimilation of self and non-self) to intolerance (rejection of self and non-self). Immunologists are aware of the power of immunologic rejection of histo-incompatible transplanted organs or tissues as well […]
