Targeting tristetraprolin in basophils: A breakthrough in allergic inflammation treatment

Inflammation is a crucial part of the body’s defense mechanism, playing a key role in fighting infections and repairing tissue damage. Basophils, a type of immune cell that makes up less than 1% of white blood cells, have recently emerged as critical players in triggering allergic responses by releasing pro-inflammatory cytokines like IL-4. Despite the established role of basophils in inflammation, the molecular mechanisms controlling their cytokine production have remained unclear. To address this gap, a group of researchers from Institute of Science Tokyo, led by Professor Kensuke Miyake, conducted a study to explore the role of tristetraprolin ...

University of Iowa study traces Ebola's route to the skin surface

Ebola is a deadly hemorrhagic disease caused by a virus that is endemic in parts of East-Central and West Africa. Most people are aware that a primary route for person-to-person transmission is through contact with bodily fluids from an infected person. But more recent outbreaks, including the 2013-2016 Ebola epidemic in West Africa, demonstrated that infectious Ebola virus (EBOV) is also found on the skin&rsquo;s surface of those who have succumbed to infection or at late times during infection. Although evidence suggests that EBOV can be passed on from skin contact with a person in the later stages of the disease, very little is known about how the virus makes its way out ...
