Inflammatory on and off switch identified for allergic asthma and COPD
From Science Codex:
Japanese researchers have made a new step toward understanding why-and how to stop-runaway inflammation for both chronic obstructive pulmonary disorder (COPD) and allergic asthma. In a new report appearing in the August 2013 issue of The FASEB Journal scientists show that two receptors of an inflammatory molecule, called "leukotriene B4," play opposing roles in turning inflammation on and off for allergic asthma and COPD. The first receptor, called "BLT1," promotes inflammation, while the second receptor, called "BLT2," has a potential to weaken inflammation during an allergic reaction. This discovery also is important because until now, BLT2 was believed to increase inflammatory reaction. Read more.
