When undertaking a study on allergen-induced anaphylaxis in mice, researchers have found that not only the immune but also the nervous system may potentially play a part in the anaphylactic response. In their study published March 17, 2023, in Science Immunology, researchers from Duke University Medical Center reported that mice undergoing anaphylaxis displayed an “extended posture behavior” similar to the one that mice exhibit when exposed to high temperatures.
It has been demonstrated that stem cell factor (SCF) and its receptor KIT play key roles in the differentiation, proliferation, survival, migration and activation of mast cells, which in turn play a central role in the development of IgE-mediated allergic diseases, including allergic urticaria and food allergy.
Mas-related G-protein coupled receptor X2 (MRGPRX2) is expressed particularly on mast cells and its activation leads to the mast cell degranulation with release of inflammatory mediators.
DUBLIN – Could a tyrosine kinase inhibitor approved for treating canine cancer offer clinical benefits in Alzheimer’s disease? That’s the bold claim AB Science SA is making, after unveiling top-line data from a phase IIb/III trial in which it reported that a subgroup of patients on a twice daily 4.5-mg/kg dose of oral masitinib experienced “a significant treatment effect” as compared with placebo after 24 weeks.
