Objective:
This review aims to study the receptor's family and functions most related to COVID-19 infection and also suggest the tissue and cell location on which the majority of COVID-19 receptors are mainly expressed.
Methods:
This systematic review is according to PRISMA guidelines. PubMed, Cochrane, SciELO, Lilacs, Web of Science, and DOAJ databases were used. Clinical trials and research articles studying receptors related to COVID-19 were included in this review. R programming language was used to elaborate charts and receptors network, and SPSS(26v) software was used to perform statistical analysis (PROSPERO: CRD42020210643).
Results:
The majority of studies on the involvement of receptors in COVID-19 included plasma receptors and G protein-coupled receptor families (p<0.05). These receptors are highly expressed in the brain (24%) and 80% of them can interact with each other in a protein network, exerting some regulatory effects on various tissues. The main influential receptor in the network of receptors involved in the COVID-19 was the EGFR and the majority of receptors were associated with pathological processes of the disease (p<0.05), including the amplification of inflammatory responses in COVID-19, which may be related to neurological disorders in some cases. Studies on receptors involved in the COVID-19 included mainly patients from the United States, Spain, and Brazil (p<0.05).
Conclusion:
Plasma receptors and G protein-coupled receptors, especially the EGFR, involved in pathological effects of the COVID-19 inflammatory process in the brain have shown significant importance in this review.

Opioid Receptors: Overview
G Protein-coupled Receptors
GPCRs are also called heptahelical, 7TM, or serpentine receptors, and consist of seven (H1-H7) transmembrane alpha-helices that span the bilayer to form a cylindrical core. The transmembrane helices are connected by three extracellular loops and three...
Adrenergic Receptors: β Subtype
Isoprenaline > Adrenaline > Noradrenaline
Neurotransmitter binding to these receptors causes activation of adenylyl cyclase resulting in increased concentrations of cAMP and modulation of calcium ion channels within the cell. They are further classified into β1, β2, and β3 subtypes.
