The pattern of early IgG response at one week post priming by MG antigens was different than that obtained for MG-specific IgA; detectable MG specific-IgG titers were shown in birds of TRTs 1, 3, and 5 at one week post priming, while the MG specific-IgA titers post one week of priming were only detected in birds of TRT 3. Here, CD79A is linked to myasthenia gravis.
