A sedentary lifestyle and obesity are important risk factors for severe COVID-19 complications and death [1, 2]. Excessive adipose tissue (AT) might contribute to more extensive viral spread with increased shedding, immune activation, and cytokine amplification [3].
Several factors secreted by contracting muscle, termed myokines, mediate the beneficial effects of exercise in a wide range of diseases, including obesity [4].
Thus, we conducted a study to explore the potential role of myokines of the fibronectin type III domain-containing family, FNDC4 and FNDC5, in mechanisms underlying the increased susceptibility to COVID-19 complications in obesity.
