The pair recently submitted a 4-year proposal to the National Institutes of Health to continue their research into the genesis and activation of B cells in rainbow trout. Zwollo notes that the collaboration provides “a great opportunity” to build on their shared interests and individual expertise. “We’re both B-cell immu- nologists,” says Zwollo, “but my focus has been on B-cell development in 2 The Crest Cobia Anyone? By Sally Mills The Crest Berret’s Restaurant and Raw Bar Vol. 4 No. 2 Summer 2002 in Williamsburg took on an air of excitement and drama on May 21st when 50 of its patrons ordered the cobia special for dinner.
