From their observations, the authors speculated that B. burgdorferi somehow subverted B cell activation in the lymph node so that the end result was a large number of plasma cells secreting antibodies of poor quality. By poor "quality," I assume that the authors meant that the affinity of the antibody for B. burgdorferi proteins was low and that the "wrong" subclasses of IgG antibodies were expressed. The most abundant IgG subclasses being produced in the draining lymph node at its most swollen state were IgG2b and IgG3. Whether other IgG subclasses would be more effective at clearing B. burgdorferi from the host and whether the affinities of the antibodies for B. burgdorferi proteins were poor still need to be determined experimentally. Perhaps a classic T-cell dependent B cell response involving the formation of germinal centers accompanied by somatic hypermutation, affinity maturation, and appropriate class switching would have led to production of "high" quality antibodies. If the authors are correct, they have revealed yet another means by which B. burgdorferi could persist in the host.
