However, exactly how commensal bacteria cause CX3CR1+ macrophages in the intestine to protrude their tentacle-like dendrites to capture antigens, triggering the immune response, was unclear. Now, a research team has shown that common bacterial metabolites pyruvate and lactate interact with the GPR31 receptor on CX3CR1+ cells, enhancing the immune response and protecting against gut pathogens. https://www.sciencedaily.com/releases/2019/01/190123131700.htm ScienceDaily: Latest Science News urn:uuid:a074c582-dd50-9151-0f9f-3e5fedd973d3 Wed, 23 Jan 2019 12:17:00 -0600 A new study confirms the urgency to tackle climate change. While it's known that extreme weather events can affect the year-to-year variability in carbon uptake, and some researchers have suggested that there may be longer-term effects, this study is the first to actually quantify the effects through the 21st century and demonstrates that wetter-than-normal years do not compensate for losses in carbon uptake during dryer-than-normal years, caused by events such as droughts or heatwaves. https://www.sciencedaily.com/releases/2019/01/190123124719.htm ScienceDaily: Latest Science News urn:uuid:4ca01098-73fc-e23a-dea1-0eb4e35d00e4 Wed, 23 Jan 2019 11:47:19 -0600 A new study establishes that patients with chronic obstructive pulmonary disease (COPD) face heightened risks of death, critical illness, and hospitalization if they develop the flu and demonstrates the beneficial effects of influenza vaccination.
