Research in the Alvarez lab is aiming to understand the biology of the Central Nervous System (CNS) barriers under homeostatic and inflammatory conditions. These barriers selectively restrict the molecular and cellular trafficking between the periphery and the CNS, but also serve as a signaling interface that actively regulates exchanges between both compartments. They are composed of the blood-brain barrier (BBB), the blood-meningeal barrier (BMB) and the blood cerebrospinal fluid barrier (BCB).

Our previous work has demonstrated that these barriers and their surrounding microenvironment (i.e: glial cells via the Hedgehog pathway) are fundamental in regulating the development of inflammatory responses within the CNS. Our laboratory studies these barriers in the context of diseases like Multiple Sclerosis by experimentally integrating in vitro, in vivo, ex-vivo and in situ assays making use of human and animal systems. These efforts are strengthened by our interaction with local and external clinical centers, which aim to harmonize our scientific endeavors with the current understanding of human diseases.
