Emerging viral infections—from bird flu to Ebola to Zika infections—pose major threats to global public health, and understanding their origins can help investigators design defensive strategies against future outbreaks. A new study provides important insights on the potential origins of the most recent outbreak of viral pneumonia in China, whichRead More →
Promoting the signalling pathway of reelin –an essential extracellular protein for the neuronal migration and synaptic plasticity- could be an effective therapeutical strategy to counterbalance the main cognitive, biochemical and behavioural alterations seen in Alzheimer’s and other pathologies associated with Tau protein, as shown in a new study with animalRead More →

Human immunodeficiency virus (HIV) damages the cells in the immune system, reducing the number of some of the white blood cells (CD4+ T cells) in the body and weakening the ability to fight everyday infections and disease. If left untreated, HIV infection eventually progresses until the immune system is tooRead More →

In 1972, the geneticist Susumu Ohno formalized the term “junk DNA” to describe DNA that do not encode protein sequences or non-coding DNA. In 2000, scientists presented the Human Genome Project confirming that around 98% of the human genome had no apparent function. Therefore, only about 2 percent of DNARead More →
Darwin said that humans and monkeys have a common ancestor (around 5-10 million years ago), freaking out creationists by the fact that humans are apes. Therefore, humans sit on the same branch of the evolutionary tree as great ape species, such as chimpanzees, our closest living primate relative. By comparingRead More →
If you think you don’t have viruses in our body because you are not sick you are totally wrong because many viruses chronically infect us without inducing any disease. The viruses living in and on the human body is known as the human virome and may infect both human cellsRead More →
Immunoglobulins (Ig) or antibodies serve as key detection molecules in the immune system. Antibodies refers to proteins that are produced in B-lymphocytes by the body’s immune system in response to foreign substances or infections, including bacteria or viruses. There are five major classes (isotypes) of immunoglobulins: IgA (immunoglobin A) IgDRead More →
