IgG subclasses specific to Staphylococcus epidermidis and Propionibacterium acnes in patients with acne vulgaris

IgG subclasses specific to Staphylococcus epidermidis and Propionibacterium acnes were determined in sera from patients with mild, moderate or severe acne and from a control group. Titres specific to S. epidermidis were all within the same range and did not differ between groups. The titres of IgG subclasses to specific to P. acnes did vary between groups. IgG1 and IgG3 were significantly higher in severe acne patients compared with moderate acne patients, while IgG2 was significantly higher in moderate and severe patients compared with controls. Titres of IgG4 did not differ between groups. The pattern of titres observed suggests that, while the antibody response to S. epidermidis is relatively harmless, antibodies to P. acnes may be involved in the pathogenesis of acne vulgaris.

Antibody Specificity

Antibodies produced by B cells are highly specific for antigen as a result of random gene recombination and somatic hypermutation and affinity maturation. As the main effector of the humoral immune system, antibodies can neutralize foreign cells. Find the latest research on antibody specificity here.
