Its main authors are Sonia Sirisi, Xabier Elorza-Vidal and Tanit Arnedo \u2013 affiliated to UB-IDIBELL and CIBERER. The work was co-directed by Xavier Gasull (Institute of Neurosciences-UB and IDIBAPS) and Ra\u00fal Est\u00e9vez (Institute of Neurosciences-UB, IDIBELL and CIBERER), in collaboration with Virginia Nunes (UB, IDIBELL and CIBERER). T<\/p>\n<p>he study concluded that ClC-2 (chloride channel), GlialCAM and MLC1 proteins (the latter two are altered in MLC) associate to form a ternary complex when astrocytes are depolarized, such as in situations of high neuronal activity. This association changes the voltage activation of the ClC-2 channel, which leads it to be open to positive potentials, allowing it to participate in the compensation of positive charges in the glial cells introducing chloride.<\/p>\n<p>Thus this work assigns a physiological function to the ClC-2 channel and allows to describe an altered pathophysiological process in MLC, which is necessary to design future therapeutic interventions. This work also hypothesizes what the biochemical function of GlialCAM \/ MLC1 proteins might be.<\/p>\n<p>S\u00f2nia Sirisi, Xabier Elorza-Vidal, Tanit Arnedo, Mercedes Armand-Ug\u00f3n, Gerard
