Humans’ Endogenous Retroviruses Influence Our Brain Development

Humans’ Endogenous Retroviruses Influence Our Brain Development





A recent article in ScienceDaily based on a publication in the journal Cell Reports describes a hot topic in neurobiology: the contribution of endogenous retroviruses (ERVs) towards human brain development (1,2). Perhaps the most famous retrovirus is HIV, the Human Immunodeficiency Virus, shown in Figure 1. Unlike HIV, however, ERVs are […]

When stress becomes deadly

Stress has long been associated with increased risk of cardiovascular disease. New research suggests that a potential explanation for this correlation is due to increased activity of the amygdala, which may upregulate bone marrow activity and arterial inflammation.

Whether it’s from upcoming exams, unpaid bills, or simply a long day at work, stress is an inevitable part of life. However, poor stress management can lead to severe health impairments, with several studies showing that chronic stress is particularly correlated with higher risk of heart disease, although scientists have […]
