Ple iotropic proinflammatory cytokines, interleukin-
1 (IL-1) and tumor necrosis factor-α (TNF-α), involved
in the regulations of various immune responses, inflammatory
processes and hematopoiesis. In the present study,
the expression levels of IL-1 and TNF-α were detected by
enzyme-linked immunosorbent assay (ELISA). Following
the cytokine blockade as a successful clinical therapy for
autoimm une diseases such as rheumatoid arthritis, the
patients are more susceptible to a variety of opportunistic
infections. IL-1 and TNF-α may be useful predictive biomarkers
of diseases and offer potential targets for therapeutic
intervention of inflammatory diseases. However,
our results showed that the plasma IL-1 level was significantly
higher in women compared to men (69.5 ± 19.8 pg/
ml in men and 80.1 ± 19.5 pg/ml in women, respectively);
the plasma levels of TNF-α were higher in men than
women (20.8 ± 4.9 pg/ml and 18.7 ± 7.1 pg/ml, respectively).
The significant gender difference of plasma interleukin-1
(IL-1) and TNF-α levels present in healthy adults in Jiangsu
Province, China (P=0.002 and P=0.015, respectively), and
may be as a hint for sex differences of susceptibility to
many diseases and elementary immune response.
