SARS-CoV-2 (Severe Acute Respiratory Syndrome Coronavirus 2) also known as 2019-nCoV (2019 Novel Coronavirus) is a virus that causes illnesses ranging from the common cold to severe diseases. SARS-CoV-2 Spike Protein is composed of S1 domain and S2 domain. S1 contains a receptor-binding domain (RBD) that can specifically bind to angiotensin-converting enzyme 2 (ACE2), the receptor on target cells. S protein plays an important role in the induction of neutralizing-antibodies and T-cell responses, as well as protective immunity.

SARS-CoV-2 (Severe Acute Respiratory
Syndrome Coronavirus 2) also known as 2019-nCoV (2019 Novel Coronavirus) is a virus that causes illnesses ranging from the common cold to severe diseases. Recently, the new B.1.1.529 variant was confirmed in South Africa and preliminary evidence suggests an increased risk of reinfection with this variant. The B.1.1.529 variant was first reported to WHO on 24 November 2021 and WHO has designated this variant as a VOC (Variant of Concern), named Omicron. There are more than 30 mutations in the spike protein.

Siglec-10 is immune system-restricted and highly expressed in peripheral blood leukocytes. Siglec-10 preferably binds to α-2,3- or α-2,6-linked sialic acid (similarity). Siglec10 is involved in the negative regulation of B cell antigen receptor signal transduction. The inhibition of B cell activation depends on PTPN6/SHP-1 (by similarity). The binding of Siglec10 to CD24 may be involved in the selective suppression of the immune response (by similarity) to risk-related molecular patterns (DAMPs) (such as HMGB1, HSP70 and HSP90). The combination of Siglec10 and CD24 may regulate the immune response of natural killer (NK) cells. Play a role in controlling autoimmunity (by similarity). In the process of initiating an adaptive immune response by CD8-α+ dendritic cells, cross-presentation is inhibited by weakening the formation of MHC class I peptide complexes. The function seems to imply the recruitment of PTPN6/SHP-1, which dephosphorylates NCF1 of the NADPH oxidase complex, thereby promoting phagosome acidification (by similarity).

Siglec-15 preferentially recognizes the Neu5Acalpha2-6GalNAcalpha- structure. Siglec-15 associates with the activating adaptor proteins DNAX activation protein (DAP)12 and DAP10 via its lysine residue in the transmembrane domain. Siglec-15 is the second human Siglec identified to have an activating signaling potential; unlike Siglec-14, however, it does not have an inhibitory counterpart.

CD22, or cluster of differentiation-22, is a molecule belonging to the SIGLEC family of lectins. It is found on the surface of mature B cells and to a lesser extent on some immature B cells. CD22 a member of the immunoglobulin superfamily. CD22 functions as an inhibitory receptor for B cell receptor (BCR) signaling. It is also involved in the B cell trafficking to Peyer’s patches in mice.

Signal regulatory protein alpha (SIRPα, designated CD172a), is also known as CD172 antigen-like family member A (CD172a), also called SHPS-1 (SHP substrate 1) and previously, MyD-1 (Myeloid/Dendritic-1), which is a monomeric about 90kDa type I transmembrane glycoprotein that belongs to the SIRP/SHPS (CD172) family of the immunoglobulin superfamily. SIRPα is Ubiquitous and highly expressed in brain. SIRPA/CD172a is immunoglobulin-like cell surface receptor for CD47 and acts as docking protein and induces translocation of PTPN6, PTPN11 and other binding partners from the cytosol to the plasma membrane. SIRPA/SHPS-1 supports adhesion of cerebellar neurons, neurite outgrowth and glial cell attachment and may play a key role in intracellular signaling during synaptogenesis and in synaptic function by similarity. SIRPα recognition of surfactants SP-A and SP-D in the lung can inhibit alveolar macrophage cytokine production.
