CDCA7's Role in DNA Methylation Maintenance Revealed in Recent Study

DNA methylation is a process in which a methyl group is attached to the cytosine base of the DNA molecule, and a major way that DNA is epigenetically marked. Epigenetic modifications can act as on-off switches to regulate gene expression and help generate diverse cell types without changing the underlying DNA sequence. It is how the body ensures that brain-related genes don't get turned on in heart cells, for example.

Swabbing Technique Reveals Diversity of Immune Cells in the Upper Airway

Scientists at La Jolla Institute for Immunology (LJI) have published the first-ever, in-depth analysis of immune cell memory in the upper airways of adult volunteers. Among these immune cells, the researcher spotted "tissue resident" memory cells, which stand ready to defend the airway from SARS-CoV-2 and other respiratory diseases.

Flu Virus Exploits Immune System Weakness to Infect Cells

The majority of influenza viruses enter animal or human cells through particular surface-based pathways. It has recently been found by researchers at the University of Zurich that some influenza viruses, both human and avian, can also enter cells through a second entry point that involves an immune system protein complex.

Scientists Identify Gene Region that Fuels Asthma Inflammation

Pollen and house dust mites are two common allergens that cause respiratory distress in asthma patients. But type-2 helper T (Th2) cells and group-2 innate lymphoid cells (ILC2s) release a class of proteins known as type-2 cytokines in response to a variety of asthma triggers. GATA-binding protein 3 (GATA3) is essential for the maturation of Th2 and ILC2.
