IL-1β and IL-6 Are Highly Expressed in RF+IgE+ Systemic Lupus Erythematous Subtype

Figure 2

SLE patients were divided into different subgroups. All the SLE patients included 3 cases from a family with RF+IgE+; the other patients were divided into 4 subgroups based on the results combination of RF and IgE. A total of 8 SLE patients with RF+IgE+ were investigated for high expression of cytokines. Note. RF+ means that RF concentration is higher than the upper-limit level of our lab reference range (20 IU/mL). IgE+ means that IgE concentration is higher than the upper-limit level of our lab reference range (150 IU/mL).
