What drives the selection of the body’s best and brightest B cells? A new study by @niaid.nih holds the answer...http://bit.ly/2KzNSTg Video: Time-lapse live cell imaging of naïve B cell immune synapses activated by high-affinity (first column) or low-affinity antigen (second column), and GC B cell immune synapses activated by high-affinity (third column) or low-affinity antigens (fourth column).

While probiotics are more popular now than ever before, experts have questioned the ingredients listed in products containing “good” bacteria that are sold online or on store shelves. In September, the FDA issued new draft guidance on labeling probiotics and dietary supplements that contain live microbes to address concerns about the accuracy of labels. What makes a probiotic a probiotic? Can consumers trust how probiotics are labeled? What do consumers need to know before taking a daily probiotic? What questions remain before probiotics can be approved as therapies for various diseases and disorders? Join Noah Palm, Jeremiah Faith, and Thaddeus Stappenbeck, leading scientists in the microbiome field, as they answer these questions and more. Right before the FBL, our page will feature related commentary (https://www.facebook.com/ScienceImmunology/videos/928015127384344/) from Sin-Hyeog Im, whose paper on the probiotic Bifidobacterium bifidum appeared in the 19 October issue of Science Immunology. Drs. Palm, Faith, and Stappenbeck will also discuss what Dr. Im’s findings mean for the future of probiotic-based treatments.6 months ago
