How exactly mast cell activation translates into the modification of behaviours is not yet completely understood. Florsheim et al. showed that even early allergic symptoms are associated with the activation of areas of the brain involved in the response to aversive stimuli. Importantly, the results ...
which can damage the natural biologic balance. One of the most significant challenges is early recognition of mast cell involvement in conditions and diseases which may present with a multitude of symptoms that are often misdiagnosed. Although appropriate referral to a specialist is essential, the li...
