...r the receptor that senses that attractant did not cluster as normal bacteria did. Disrupting chemotaxis could be a route to attacking biofilms, a common type of bacterial interaction in which they form a colony that is resistant to antibiotic drugs and chemicals, the researchers said. Biofilms pose a common...Towards an AIDS vaccine: unusual antibody that targets HIV described by scientists at TSRI

The 2G12 antibody forms an unusual "dimer" interface where two antibodies create an unusual multivalent binding interface with multiple binding sites that recognizes an unusual arrangement of 2-3 "oligomannose" sug...Muscle protein has role in nerve disorders
...glycan reduces the density of sodium channels that cluster at each node and are critical for normal transmission of nerve impulses. "The slowing in the time it takes for a signal to travel along the nerve, is really interesting," Campbell said.

As a result, people and mice lacking the gene have thin, sparse hair that is fragile and breaks easily.
