Dok-1 regulates mast cell degranulation negatively through inhibiting calcium-dependent F-actin disassembly.

Clin Immunol 2022 05 11;238:109008. Epub 2022 Apr 11.

Key Laboratory of Precision Nutrition and Food Quality, Key Laboratory of Functional Dairy, Ministry of Education, College of Food Science and Nutritional Engineering, China Agricultural University, Beijing 100083, PR China. Electronic address:

In food allergies, antigen-induced aggregation of FcεRI on mast cells initiates highly ordered and sequential signaling events. Dok-1(downstream of tyrosine kinase 1), undergoes intense tyrosine phosphorylation upon FcεRI stimulation, which negatively regulates Ras/Erk signaling and the subsequent cytokine release, but it remains unclear whether Dok-1 regulates Fc-mediated degranulation. In this study, we investigated the role of Dok-1 in FcεRI-mediated degranulation. Read More

Clin Immunol 2022 01 27;234:108896. Epub 2021 Nov 27.

Department of Cell Biology, Genetics and Physiology, University of Malaga (UMA), The Institute of Biomedical Research in Malaga (IBIMA), Málaga, Spain. Electronic address:

Little is known about the causes and mechanisms of ectopic immune responses, including different types of hypersensitivity, superantigens, and cytokine storms. Two of the most questionable phenomena observed in immunology are why the intensity and extent of immune responses to different antigens are different, and why some self-antigens are attacked as foreign. The secondary structure of the peptides involved in the immune system, such as the epitope-paratope interfaces plays a pivotal role in the resulting immune responses. Read More
