Introduction: TNF receptor 1 appears to have a key role in the autoimmune response. Some MS patients have mutations in this receptor. Our goal is to understand how they affect some of the most common mutations in the course of the disease.
Results:
a) the substitution R92Q reduces the age of onset of multiple sclerosis, but slows its progression

Introduction: The data on the effect of NO (or donors thereof) in myocardial infarction and the mechanisms by which it acted were contradictory at baseline. On the other hand, there was virtually no information on the operation of transduction system NO / cGMP on the heart during myocardial ischemia and reperfusion. Nor it is well known how the synthesis of cyclic GMP in the myocardial tissue is regulated under physiological conditions.
Results:
a) Synthesis of cyclic GMP decreases during myocardial ischemia and reperfusion.
b) Administration of substances that stimulate the synthesis of cyclic GMP by the end coronary occlusion normalized levels of endogenous cyclic GMP and reduces infarct size. Moreover, the beneficial effects of NO in these same models appear to be mediated by cyclic GMP.
c) For the first time in cardiomyocytes it has been found that a significant fraction of ‘soluble’ guanylyl cyclase enzyme is membrane associated. Furthermore, correlation studies carried out indicate that cyclic GMP synthesis in these cells could depend largely enzyme of this fraction membrane located.

Introduction: At the beginning of the study of nitric oxide (NO) in the (beginning of the 90’s) nervous system it was assumed that only NO synthase containing neurons.
Results:
a) The glial cells, contrary to what was assumed at the time of study, also contain constitutive NO synthase (apparently similar to neuronal, NOS1).
b) Although the enzyme is in vitro neuronal indistinguishable, the NO synthase is modulated differently in neurons and glial cells.
c) The activity transduction system NO / cGMP glial varies in different areas of the central nervous system and is particularly relevant in the cerebellum.

Introduction: Certain data indicated the existence of amino acid neurotransmitter release independent of Ca2+ in the synaptic terminals. The possibility of the involvement of transport systems into the cell in this process are discussed.
Results:
a) conveying systems amino acid neurotransmitters might be involved in their release during synaptic transmission (running in reverse as efflux systems).
