Two cationic proteins, a neutral phosphatase (NP-tase) and a 70-kD protein (p70) were isolated from Staphylococcus aureus by ion exchange chromatography. We compared their properties to those of the well established B cell mitogen of whole, fixed Staph. aureus strain Cowan I cells (SAC). Both purified proteins were able to induce immunoglobulin synthesis in PBMC cultures of healthy donors. NP-tase and p70 also induced immunoglobulin synthesis of PBMC from those patients with CVID who were also… CONTINUE READING
