In a new publication led by Dr. Albert Giralt, the researchers discovered the interaction between a transcription factor identified as “Helios” and a protein called “WDFY1” that could help elucidate the link between immunity and schizophrenia . Schizophrenia is an incurable mental illness characterized by relapsing episodes of psychosis. This disorder affects approximately 1% of […]

A reported case study in a Colombian woman , member of a family carriers of a mutation in the presinilin 1 gene which leads to early onset Alzheimer’s, has shown that a certain mutation in the gene APOE3 can protect from the cognitive decline associated with Alzheimer’s disease. This woman was already aged 70 but […]

What differentiates us from our closest relatives and how are these differences caused? Scientists are trying to answer this question by comparing the genomic information of us and our closest relatives. Yet, we are far from having a genomic explanation that justifies the observed phenotypic differences. Human Accelerated Regions (HARs) However, some findings bring us […]

Neurobiology

Myelin is a lipid-rich substance that surrounds the axons of the neurons, which would be like the “wires” of the nervous system. This fatty structure serves to insulate the axons and to increase the speed with which electrical impulses, the so-called action potentials, pass along the axon. The myelinated axon can be compared to an […]

Sex and the brain

An interesting question is whether the brains of gay and straight people are the same or different. One study found that they are slightly different and that the brains of gay men, in the aspects analyzed, are more similar to those of heterosexual women. This would support the idea that sexual orientation is a biological […]
