Endothelial senescence and their pleiotropic effects onto inflamatory processes, inmunological response and angiogenesis.

Identification at the molecular level of pathways and proteins associated with the senescence of endothelial cells linked to aging and inflamatory responses. New candidate targets for therapeutic intervention at the clinical level and as new molecular moieties for nanomedicine approaches to improve aging related pathologies caused by endothelial inflamatory based senescence.

Immunologic lesional mechanisms in late adverse reactions against bioimplants.

The late clinical manifestations that arise when bioimplants are applied seem to have an immunologic basis. We are studying both the histological characteristics and the lesional mechanisms of the most frequently used implants. We try to analyze the role that bacteria may have in the induction and/or maintenance of these reactions and the possible correlation between particular HLA haplotypes and the adverse effects.

Predictive kit to detect the possible establishment of late adverse effects related to bioimplants used in clinical practice.

A high variability in the prevalence of adverse effects with an immunologic basis seems to be related with any implant used in clinical practice. We have managed to find a particular association of HLA haplotypes that increase the risk for developing these effects up to 600 times. We are nowadays working on setting up a safe and reliable biochip or kit which predicts this risk easily in a routine test.

Immunobiology and immunopathology of recurrent pregnancy loses and spontaneous loses.

Around 2-3% of reproductive-age couples suffer recurrent pregnancy loses. Almost 18% of couples that wish to have children suffer infertility problems. Simultaneously, 2-3% of all pregnant women are diagnosed with spontaneous loses. The expression of HLA molecules, specially type G, the degree of trophoblastic apoptosis, the outsourcing of new neoantigens such as phospholipids, the balance between Th1/Th2/Th3 cytokines, the type and quantity of CD4+CD25+Foxp3+ lymphocytes, the kind and the activity of uterine NK cells (uNK) cells, the presence or absence of blocking antibodies, and other mechanisms play different roles in the achievement of the so-called "tolerant microenvironment" needed to develop a normal pregnancy. Therefore, both autoimmune and alloimmune mechanisms are important. We aim at studying which isolated, and specially associated, anomalies can be identified as risk markers to be able to evaluate possible treatments.

The new technology allows more sensitive detection of scleroderma patients' autoantibodies, which are related to the severity and progression of the disease.

Researchers have used an innovative protocol to identify people with this autoimmune disease who have a higher risk of cancer.

It will allow the promotion of research on systemic autoimmune-based diseases that especially affect women of childbearing age and, therefore, can also appear during pregnancy.
