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.

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.

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).

Abstract:

Dr. Francisco A. Cubillos is a distinguished scientist with a strong background in Genetics, Molecular Biology, and Ecology. He earned his PhD in 2010 from the University of Nottingham, UK, working under the esteemed supervision of Prof. Edward J. Louis and Dr. Gianni Liti. During his doctoral studies, Dr. Cubillos focused on unraveling the genetic architecture of complex traits in the model organism Saccharomyces cerevisiae. His research played a pivotal role in identifying key genes responsible for phenotypic variations among strains. This work led to the publication of nine impactful manuscripts, showcasing his expertise and contributions to the field.

After completing his PhD, Dr. Cubillos pursued postdoctoral research at the INRA-Versailles Research Centre in Paris, France. Under the mentorship of Dr. Olivier Loudet, he explored the model organism Arabidopsis thaliana, investigating natural variation in expression traits and the role of non-coding regions in plant adaptation to extreme environments, specifically drought stress. Driven by his passion for understanding the molecular basis of expression differences, he employed cutting-edge 'omics' approaches such as RNA-Seq, DNA-Seq, and epigenome sequencing. It was during this time that Dr. Cubillos received a prestigious returning grant from CONICYT, allowing him to return to Chile and establish his own research group.

Currently, Dr. Cubillos leads a dynamic research line that combines Ecology, Genetics, and Molecular Biology. His primary focus lies in studying native ethanol-tolerant yeast from Patagonia, with an emphasis on species such as S. eubayanus, S. uvarum, and L. cidri. The Cubillos lab is actively engaged in multiple ongoing projects aimed at generating novel lager hybrids by leveraging the vast genetic diversity of S. eubayanus from Patagonia. These initiatives involve utilizing diverse genetic improvement techniques, transitioning from studying yeast ecology in the wild to exploring their biotechnological applications.

Dr. Cubillos' exceptional research contributions have been recognized through numerous research and international collaboration grants. His notable accolades include being named an EMBO Global Investigator, a TWAS Young Affiliate, and receiving the distinguished titles of 2022 Best Chilean Young Scientist and Ciencia de Frontera Researcher by the National Science Academy. So far, Dr Cubillos has published over 50 WoS Manuscripts.

Dr. Cubillos' research endeavors continue to push the boundaries of knowledge in his field, fostering collaborations, and driving advancements in Ecology, Genetics, and Molecular Biology.

The aim of the Laboratory of Mycology is to study new natural compounds with antifungal activity against the phytophatogenic fungus Botrytis cinerea and also to determine the mechanisms in the adhesion and germination process, early steps in the infection of their host. These studies constitute the essential scientific basis to design new strategies to control this pathogen.
