CO2: Immunopathologies, Inflammatory Rheumatic Diseases and Biomarkers in Neoplastic Processes

Our group arises from the close and long-lasting collaboration between basic and clinical researchers in the field of Immunology and Rheumatology. Several members of the group have a long tradition in the study of B lymphocyte populations and their differentiation into plasma cells (PCs), responsible for the production of antibodies and therefore humoral immunity. The maturation process from B lymphocytes to CPs goes through a series of phases in which the physiological and phenotypic characteristics of the CPs gradually change until reaching final maturity. In this stage, in which the CPs produce high affinity antibodies against a specific antigen, they are directed and selected in final host tissues, such as the bone marrow, in which said cells, although they lose their ability to proliferate, acquire a status long-lived Our group, in addition to studying the characteristics of the different phases of B lymphocytes and PCs in humans, also studies the transcriptional regulation of a transcription factor, called PRDM1, key in this cell differentiation process. The expression of alternative isoforms to PRDM1 has been over-expressed in multiple myeloma, the tumor counterpart of PCs.

On the other hand, the objective of our group is the study of systemic autoimmune diseases, fundamentally but not exclusively, Rheumatoid Arthritis (RA) and Systemic Lupus Erythematosus (SLE). Although the pathophysiological mechanisms of autoimmune diseases are unknown, they present various autoantibodies as markers of the disease. Our group tries to identify new cellular and/or molecular biomarkers that allow us to predict and reduce the peaks of the disease through the development and design of possible new therapies. The populations of B lymphocytes and autoreactive PCs present in these patients, in which, as previously mentioned, the group has extensive experience, seem to be a good starting point for study to try to develop therapies that eliminate or lessen the adverse effects of these diseases.

Lines of research
  • B lymphocytes and their differentiation to plasma cells. Study of the phenotypic characteristics and transcriptional factors that determine the differentiation of B lymphocytes to plasma cells in different tissues and degrees of maturation. Transcriptional factors that may be involved in the development and maintenance of lymphomas and/or myelomas.
  • Protein machinery involved in exocytosis or cell secretion. We characterize the proteins that may be key in the mechanism of antibody secretion by plasma cells. The proteins that make up the cellular secretory machinery are involved in any cellular secretion process, including everything from exosomes to interleukins.
  • B lymphocytes and autoreactive plasma cells. We studied these cell populations in patients with rheumatic autoimmune diseases, mainly Systemic Lupus Erythematosus and Rheumatoid Arthritis. Phenotypic and molecular characterization of these populations.
  • Study of exosomes and gene expression as biomarkers in multiple myeloma and other neoplasias.
