#CB2 BOOK END REGISTRATION#

Every function in our bodies requires balance, or homeostasis, to perform at maximum capacity. Your CB2 receptors are most commonly found on immune cells.Ĭannabinoid receptors are an essential component of the body's endocannabinoid system (ECS). The body has two main cannabinoid receptors - the CB1 receptor and the CB2 receptor. I have followed all appropriate research reporting guidelines and uploaded the relevant EQUATOR Network research reporting checklist(s) and other pertinent material as supplementary files, if applicable.An important protein in the body's endogenous cannabinoid system that is heavily involved in the body's immune system, and plays an important role in fighting inflammation.

The authors have declared no competing interest. These late immunometabolic inflammatory changes and unresolved immune cell defects, if persistent, may contribute to “long COVID”. Immune recovery is complex, with profound persistent cellular abnormalities correlating with a change in the nature of the inflammatory response, where signatures characteristic of increased oxidative phosphorylation and reactive-oxygen species-associated inflammation replace those driven by TNF and IL-6.

Viral load does not correlate with the development of this pathological response, but does with its subsequent severity. Such early evidence of inflammation suggests immunopathology may be inevitable in some individuals, or that preventative intervention might be needed before symptom onset. Those presenting to hospital had delayed adaptive responses and systemic inflammation already evident at around symptom onset. In a study of 207 SARS-CoV2-infected individuals with a range of severities followed over 12 weeks from symptom onset, we demonstrate that an early robust immune response, without systemic inflammation, is characteristic of asymptomatic or mild disease.
