CD4+ T cells have been highlighted in the scientific literature for the important role they play in the immune response to lung infections. However, an article published in the journal Cell Reports shows that an imbalance in the volumes of these defense cells in different parts of the lung in response to infection can do more harm than good. The study described in the article involved infecting mice with hypervirulent tuberculosis and influenza. The authors [...]

A study led by Brazilian researchers shows that people who have had Zika run a higher risk of subsequently having severe dengue and being hospitalized. The finding is highly relevant to the development of a zika vaccine. According to the scientific literature, a second infection by any of the four known dengue serotypes is known to be typically more severe than the first, but until now no correlation between this fact and the occurrence of other diseases had been investigated.  An [...]

Researchers from University of California San Diego, as part of a large collaboration with scientists around the world, have developed a new search tool to help researchers better understand the metabolism of microorganisms. Microbes are key players in virtually all biological and environmental systems, yet limitations in current techniques used to study microbial metabolism make it difficult to decode their interactions and activities. The new research, published February 5, 2023 in Nature [...]

A team of international scientists has published a description of a novel jellyfish species with a unique red stomach resembling the Cross of St. George. About the jellyfish: The St. George's Cross Medusa, named after the red cross emblem of England, has been identified as Santjordia pagesi (refers to Saint George in Catalan), a newly described species of medusa. Compared to other medusa species, the St. George's Cross Medusa is relatively smaller, measuring approximately four inches [...]

A protein that has been widely studied owing to its association with neurodegenerative diseases such as amyotrophic lateral sclerosis (ALS) is also linked to medulloblastoma, a type of central nervous system cancer. Medulloblastoma is one of the most common and aggressive brain tumors in children, arising from undifferentiated cells during early neural development. A study led by a group of Brazilian scientists has shown in vitro and in vivo that the gene VAPB is linked to cell [...]

People who have had zika run a higher risk of subsequently having severe dengue and being hospitalised, a new study has showed. The analysis by a team of Brazilian researchers showed that patients with a history of zika infection had a 2.34 times higher risk of developing severe dengue. They also had a 3.39 times higher risk of hospitalisation compared to the controls (subjects with no dengue and no zika history). Relatively advanced age (over 59) was also a higher risk factor for severe [...]
