“…The innate immune system is present in simple life forms and is largely used in more developed life forms such as vertebrates including rodents and humans ( Riera Romo et al., 2016 ). The innate immune system functions include recruiting immune cells to infections sites, producing cell signaling molecules called cytokines, identification of foreign substances including bacteria, viruses, and protozoa, activation of complement cascades, clearing antibody complexes and dead cells, activating the adaptive immune system through antigen presentation of antigen presenting cells (APCs), altering the vascular system to protect the spread of pathogens or damaging substances, and regulates non-immunological functions such as cognition, and mood, and sleep ( Zielinski and Krueger, 2011 ; Filiano et al., 2015 ; Riera Romo et al., 2016 ; Masih et al., 2019 ). Based on the visual observations of Celsius and Galen near the beginning of the common era, five cardinal signs of inflammation were identified including rubor (i.e., redness), tumor (i.e., swelling), calor (i.e., increased temperature), dolor (i.e., pain, and function laesa (i.e., loss of function) ( Tracy, 2006 ).…”
