Effects of exercise on TLR2 and TLR4. For chronic resistance exercise, 67% of studies reported a reduction of TLR4 and/or TLR2 expression. For acute resistance exercise, 75% of studies revealed a decrease in the expression of these receptors. For chronic aerobic exercise, 58% of studies reported a reduction in TLR4 and/or TLR2 expression and 25% found an increase in the expression of TLR4 and/or TLR2. For acute aerobic exercise, 40% of studies showed a decrease and 40% reported an increase. Regarding combined exercise, 50% of studies reported a reduction in the expression of the receptors
