Abstract

Background Chronic granulomatous disease (CGD) is a primary immune deficiency characterized by a defect in reactive oxygen species production. Although the effect of CGD mainly reflects on the phagocytic compartment, B-cell responses are also impaired in patients with CGD. Objective We sought to investigate how defective gp91phox expression in patients with CGD and CGD carriers might affect the B-cell compartment and maintenance of long-term memory. Methods We studied the B-cell compartment of patients with CGD in terms of phenotype and ability to produce reactive oxygen species and proliferate on stimuli differently directed to the B-cell receptor and Toll-like receptor 9. We further studied their capacity to maintain long-term memory by measuring cellular and serologic responses to measles. Results We show that the memory B-cell compartment is impaired among patients with CGD, as indicated by reduced total (CD19+CD27+) and resting (CD19+CD27+CD21+) memory B cells in parallel to increased naive (CD19+CD27-IgD+) B-cell frequencies. Data on CGD carriers reveal that such alterations are related to gp91phox expression. Moreover, proliferative capabilities of B cells on selective in vitro stimulation of B-cell receptor or Toll-like receptor 9 pathways were reduced in patients with CGD compared with those seen in age-matched healthy control subjects. Significantly lower measles-specific antibody levels and antibody-secreting cell numbers were also observed, indicating a poor ability to maintain long-term memory in these patients. Conclusion Altogether, our data suggest that patients with CGD present a defective B-cell compartment in terms of frequencies of memory B cells, response to in vitro stimulation, and maintenance of long-term antigen-specific memory.
