Study shows why antihistamine drugs fail to control severe itch in eczema patients

In addition to a skin rash, many eczema sufferers also experience chronic itching, but sometimes that itching can become torturous. Worse, antihistamines -- the standard treatment for itching and allergy -- often don't help.

Targeting TAAR5 can provide a new treatment opportunity for neurodegenerative disorders

St Petersburg University researchers, led by Professor Raul R. Gainetdinov, Director of the Institute of Translational Biomedicine and Academic Supervisor of the St Petersburg University Hospital, have found a new role for recently discovered neurotransmitter system that uses the trace amine-associated receptor 5 (TAAR5) for neurotransmission.

Study shows how mast cells regulate calcium levels to control the immune response

Instead of protecting us, the immune system can sometimes go awry, as in the case of autoimmune diseases and allergies. An Ludwig-Maximilian-Universitaet (LMU) in Munich team has dissected how mast cells regulate their calcium levels to keep the immune response under control.
