CO16: Genetics, Epigenetics and Transcription in Brain Diseases

The group is led by a specialist in Immunology, and in recent years our group has been analyzing the regulatory functions of the LAT and NTAL membrane adapters, as well as their relationship with the Lck kinase in the transmission of intracellular signals associated with immune receptors. . Our lines of research aim to deepen the knowledge of the regulatory functions of intracellular signals in lymphocytes, and analyze the implications in some immune-based pathologies such as rheumatoid arthritis (RA).

Our lines of research include in vitro studies, through the use of tumor cell lines, work with mice, and analysis of lymphocytes from healthy donors and patients with immune-based pathologies. We have ongoing international collaborations with groups in France (Drs. Bernard and Marie Malissen, CIML, Marseille, France), UK (Dr. Michael Dustin, Univ. of Oxford, UK) and Poland (Dr. Arkadiusz Miazek, Univ. of Wrocław, Poland). Our work may be useful not only for a better understanding of the molecular mechanisms governing T cell activation, but also for gaining insight into altered immune mechanisms in RA and potentially other immune-based pathologies.
