Integrative insights into PNI: Low-grade chronic inflammation, skeletal muscle wasting, and brain impairments.

Skeletal muscle has been recognized as an endocrine organ which communicates with different systems, including the brain. In conditions , the skeletal muscle can be negatively impacted, culminating in its quantity (mass) and quality (function) losses, referred to here as muscle wasting. The inflammatory milieu, as well known, also impairs the brain function, however there are some particularities involving skeletal muscle-brain crosstalk, including cognitive function and mental health impairments (PNI) is an important field of neuroendocrine-immune-behavior science and an approach between PNI, and the movement science, or kinesiology, field can enrich future research about the relationship between skeletal muscle wasting and brain health. Thus, in this short review, we present an overview about the interplay between skeletal muscle, inflammatory mediator markers, and brain function with the purpose to strengthen the ties between kinesiology and PNI research to enhance futures discoveries and advances in health sciences.
