News at a glance: A win for obesity drugs, NIH unionization roadblocks, and Mexican fireflies under threat
CONSERVATION Researchers raise alarm over threat to Mexican fireflies Scientists from the International Union for Conservation of Nature (IUCN) last week delivered a letter to the Mexican government requesting it regulate tourism centered on the threatened firefly species Photinus palaciosi . Endemic to Mexico’s Tlaxcala forests, P. palaciosi is one of the few species that glow in synchrony, offering an annual spectacle that attracts thousands of visitors during summer mating season. The letter describes how littering, artificial light, and noise interfere with the insects’ courtship and eg...

UCLA-led team gets $8.4 million NIH grant to probe mysteries of Valley Fever
Why do some people infected with Valley Fever develop a potentially fatal form of the disease that ravages their body while most experience only mild symptoms or none at all?A team led by UCLA ’s Dr. Manish Butte has been awarded an $8.4 million grant from the National Institute of Allergy and Infectious Diseases to study this and other questions related to genetic risk factors and immune responses to the disease, which occurs when people breathe in microscopic spores of the fungusCoccidioides that are present in soil.First identified in Argentina in the late 1800s, Valley Fever today is seen in a geographic swath that s...

Surface (S) Layer Proteins of Lactobacillus acidophilus Block Virus Infection via DC-SIGN Interaction
We describe the unexpected binding of S-layer to cells devoid of DC-SIGN but also confirm that the presence of DC-SIGN was essential for S-layer’s antiviral activity. S-layer protein exerted its antiviral effect with different kinetics than mannan, a known viral inhibitor that also acts on DC-SIGN (Yu et al., 2017). Together our results suggest that inhibition of viral entry by S-layer occurs via a novel S-layer/DC-SIGN interaction. Materials and Methods Isolation of S-Layer Proteins S-layer proteins were extracted from overnight cultures of L. acidophilus ATCC 4356 cells grown in MRS medium at 37°C by usi...
