Up today there exist a number of drugs able to inhibit the acute pain. Nevertheless, these drugs are not capable of inhibiting completely chronic pain types. Even though there exist abundant knowledge about the pain pathways to the cerebral cortex,   neither the neurotransmitters participating in these pathways nor the regulatory mechanisms involved is known. Furthermore, quite a few is also known about the mechanisms involved in the codification and discrimination of tactile and painful sensations. Additionally, is also poorly understood the plastic changes involved in the response of the organism to chronic pain. This kind of interrogate has leaded our Lab to the study chronic neuropathic and arthritic chronic pain in animal models. A typical chronic pain is produced during a migraine episode. Once initiated, this pain is maintained in time due to peripheral and central sensitization. Even though the physiopathology of migraine has been deeply studied, their genesis and the mechanisms of central sensitization are still unknown. Into this topic, we development an system for long lasting drug delivery based in polymeric nanoparticle.

The Laboratory of Neural Systems is devoted to the study of the genesis and the regulation of the respiratory rhythm in mammalian neonates. Our long-term goal is to determine the biological basis underlying the effects of perinatal nicotine exposure upon the neonatal respiratory neural network. This approach is a paradigm for studying the mechanisms that relate a known population risk, as maternal tobacco smoking, with a higher rate of central nervous system disfunctions as those observed in the Sudden Infant Death Syndrome. We combine electrophysiological and morphological techniques using in vivo as well in vitro preparations (isolated brainstem-spinal cord preparation and brainstem slices).

Our research is focused on the elucidation of the molecular elements involved in adaptation of microorganisms to environmental changes. We are especially interested in characterization of the oxidative stress response of acidophilic bioleaching bacteria used in the recovery of metals from sulfide ores.  These microorganisms are a suitable model to study this response because of they are exposed to very highly oxidative conditions such as very acid pH and extremely high metal concentration.

Abstract
Injury of sensory axons at peripheral nerves endings produces functional changes in the damaged neurons.  These changes include an abnormal firing of nerve impulses, both spontaneous and evoked, causing anomalous sensations like dysesthesias and neuropathic pain.  Neuropathic pain is to a large extent refractory to treatments with traditional analgesics and anti-inflammatory drugs.  Unlike inflammatory pain, many of the molecular determinants associated with the development and maintenance of neuropathic pain are still poorly understood.  Cold allodynia (pain caused by a stimulus of innocuous cold) and hyperalgesia to cold (increased sensitivity to a potentially painful cold stimulus) are two common forms of peripheral neuropathic pain.  Thermosensitive TRP (Transient Receptor Potential) channels and several K channels have been proposed to be involved in this phenomenon.  The main goal of our research is to determine the cellular and molecular bases underlying the altered transduction of thermal stimuli in damaged primary sensory neurons, and to clarify the role of these thermosensitive ion channels in the biophysical modifications occurring in nociceptors and thermoreceptor neurons following injury.

Research
Our main interest is the metabolic status associated to cancer formation and progression. We have a particular interest in mitochondria and its participation in the generation of a metastatic phenotype. In this respect, we are investigating contribution of endogenous metabolites (i.e. lactate) to cancer progression and mitochondrial redox status.
