If we analyze the CD21480 file, of SARS CoV 2 Spike S1-RBD, we can understand how much the binding domain of the receptor of the S1 subunit, of the Spike (S) protein, contains a list of highly pathogenic infectious agents.
CoV S protein is an envelope glycoprotein that plays the most important role in viral attachment, fusion and entry into host cells and serves as a primary target for the development of neutralizing antibodies, viral entry inhibitors and vaccines.
It is synthesized as a precursor protein that is cleaved into an N-terminal S1 subunit (700 amino acids) and a C-terminal S2 subunit (600 amino acids) which mediates membrane attachment and fusion, respectively.
Three S1 / S2 heterodimers assemble to form a trimer peak protruding from the viral envelope.
The S1 subunit contains a receptor binding domain (RBD), while the S2 subunit contains a hydrophobic fusion peptide and two heptad repeat regions.
S1 contains two structurally independent domains, the N-terminal domain (NTD) and the C-terminal domain (domain C).
Depending on the virus, the NTD or the C domain can act as a receptor binding domain (RBD).
While murine hepatitis virus (MHV) RBD is found in the NTD, most other CoVs, including SARS-CoV-2, use the C domain to bind their own receptors.
Recent studies have found that the receptor-binding domain (RBD) of the SC2-S protein binds strongly to human and bat angiotensin-converting enzyme 2 (ACE2) receptors.
Furthermore, SARS-CoV-2 RBD showed significantly higher binding affinity for the ACE2 receptor than SARS-CoV RBD.
Due to the key role of the RBD protein S in viral attachment, it is the main target for antibody-mediated neutralization.

In the viral envelope: 0044423, Virion Component, you can read the viral composition of S1.
Conclusion / consideration:
INFLUENCE A / B / C = The co-presence of all three influenza viruses explains how they have been skilfully used, under the radar, by SC2; forming a highly infectious pelvis, especially in frail and elderly people.
FLAVIVIRUS NS4A / NS2B = ssRNA positive single-stranded RNA virus, belonging to the Flaviviridae family. They result in a variety of different diseases with fever, sometimes severe encephalitis and / or hemorrhagic fever. Dengue virus, Zika, and yellow fever also belong to this family. The Flaviivrus virus is divided into 2 clades: the first is given by viruses transmitted by a vector and while the second clade is given by viruses without the known vector. The vector clade, in turn, can be divided into a mosquito-borne clade and a tick-borne clade. The mosquito group can be divided into two branches: one branch contains neurotropic viruses,
often associated with encephalitic disease in humans or livestock. The second branch is given by non-neurotropic viruses associated with haemorrhagic disease in humans and primates.
PNEUMOVIRUS = RNA negative single-stranded virus, belonging to the order Mononegavirales, family Pneumoviridae. The type species is the human respiratory syncytial virus, an important causative agent of both infantile bronchiolitis and pneumonia.
ARENAVIRUS = RNA virus, ambisense, which infects rodents and occasionally humans. Arenaviruses cause human disease and vary in severity. Aseptic meningitis, a serious human disease that causes inflammation that covers the brain and spinal cord, can result from the lymphocytic choriomeningitis virus. Hemorrhagic fever syndromes, including Lassa fever, are derived from infections such as Guanarito virus, Junin virus, Lassa virus, Lujo virus, Machupo virus, Sabia virus, or Whitewater Arroyo virus. Glycoprotein (GP) is synthesized as a precursor molecule. It is divided into three parts: GP1, GP2 and a stable signal peptide (SSP). These reactions are catalyzed by cell signal peptidases and the cellular enzyme Subtilisin Kexin Isozyme-1 (SKI-1) / Site-1 in Protease (S1P). These processes are essential for fusion competence and the incorporation of mature GP into nascent virion particles.
PARAMIXOVIRUS = have a single-stranded RNA. Parainfluenza viruses, mumps virus, measles virus and human respiratory syncytial virus belong to this family.
HIV Gp120 = Gp120 is a viral glycoprotein present in the pericapsid of the HIV virus, It is an essential protein for the entry of the virus into cells, it plays a fundamental role in cell adhesion through receptors of the DC-SIGN type, heparan sulfate and a specific interaction with CD4 of helper T lymphocytes.
EIAV Gp90 / Gp2b = equine infectious anemia, classified in the family Retroviridae, in the subfamily Lentivirinae (which also includes the sheep Visna-maedi viruses, arthritis - caprine encephalitis, and the viruses responsible for the infection of humans, monkeys, felines and bovine immunodeficiency) .
HEPATITE C = HCV belongs to the hepacivirus genus in the Flaviviridae family and primarily affects the liver. Co-infection with HIV is very common.
HERPESVIRUS = Herpes simplex virus (Varicella-zoster virus); latency site: nerve endings of the CNS. Characteristic of this family of viruses is that it no longer leaves the host after the first infection and nestles in a cell type of the organism, causing a so-called latent infection. This family is also linked to the Epstein-Barr virus; its seat of latency lies in the lymphoid cells.
CITOMEGALOVIRUS = The genus includes viruses that infect various species of primates, including humans. The two cases in which serious complications can occur are the pregnant patient and the immunocompromised patient. The latter, for example, can undergo chorioretinitis, esophagitis, hepatitis and, especially for reactivation of the virus from the latency phase, encephalitis and pneumonia.
ARTERIVIRUS Cp4 = These proteins, collectively referred to as "replicase / transcriptase" or, for simplicity, simply "replicase", are encoded by open read frames 1a and 1b (ORF1a and ORF1b) of the arterivirus genome. Furthermore, the family includes viruses of veterinary interest with high genomic variability, capable of causing persistent infections with prolonged viremia and the ability to replicate in macrophages. (It is no coincidence that this virus is always found in laboratory experiments carried out with animals in vivo).
CHORDOPOXVIRUS = This is a Chordopoxvirinae family of viral fusion proteins. A Vaccinia virus protein has been shown to function as a viral fusion protein that mediates cell fusion.
PROXVIRUS P35 / Ag35 / A14 / A28 = The smallpox and alastrim viruses also belonged to this family, diseases that have now been eradicated, but still strangely present in the viral envelope of SC2.
BACULOVIRUS Gp64 / E56 / E66 / E25 / EC27 / E18 = The envelope fusion protein GP64 is an essential baculovirus protein required for cell-to-cell infection transmission. Baculoviruses infect insects (such as mosquitoes, linked to malaria), with over 600 host species. In the 1940s, baculovirus was widely used and studied as a biopesticide in cultivated fields. Since the 1990s they have been used to produce complex eukaryotic proteins in insect cell cultures (Sf21, High Five cells). These recombinant proteins have been used in research and as vaccines in both human and veterinary medical treatments (e.g., the most widely used vaccine for the prevention of H5N1, avian influenza in chickens that has been produced in a baculovirus expression vector ). More recently it has been discovered that baculoviruses can also be transduced into mammalian cells, through the use of VLP / Sf21 particles suspended in a yeast culture inside which mammalian cells are present.
CORE Gp120 = Gp120 is a viral glycoprotein present in the pericapsid of the HIV virus. It is an essential protein for the entry of the virus into cells, it plays a fundamental role in cell adhesion via DC-SIGN type receptors, heparan sulfate and a specific interaction with CD4 of helper T lymphocytes.
RHABDOVIRUS = Bats are carriers of the Lyssavirus, or rabies virus, which is responsible for rabies and vesicular stomatitis in cattle and horses. The viral particle is wrapped in a fatty membrane; it is shaped like a “bullet” (70 by 180 nm) and contains a single helical strand of ribonucleic acid (RNA). The pathogen of rabies is a Lyssavirus with different genotypes; Genotype 1 is the classic rabies virus that can also cause vesicular stomatitis.
VSV MATRIX = The vesiculovirus matrix protein family consists of several matrix proteins of the vesicular stomatitis virus, also known as VSIV or VSV. The matrix (M) protein of the virus causes many of the cytopathic effects of VSV, the M protein also induces apoptosis (cell death). These proteins play an important role in the assembly and budding of VSIV virions. Their main role is to help assemble the virus. They begin by disrupting host cell transcription by inhibiting nuclear export of mRNA through direct interaction with the host's RAE1 -NUP98 complex. This inhibits the signaling of interferon and thus the creation of an antiviral state in virus-infected cells. In turn, this induces cell rounding, disorganization of the cytoskeleton and apoptosis in the infected cell.
VESICULOVIRUS = As with RHABDOVIRUS, this virus is linked to the rabies virus, it also causes vesicular stomatitis.
TROMBUSVIRUS P19 = RNA silencing suppressor p19 (also known as the Tombusvirus P19 core protein and 19 kDa symptom severity modulator) is a protein expressed by the ORF4 gene in the tombusvirus genome. The p19 protein acts as a counter-defense strategy, specifically binding 19 to 21 nucleotide double-stranded RNAs that function as small interfering RNAs (siRNAs) in the RNA silencing system. By sequestrating siRNA, p19 suppresses RNA silencing and promotes viral proliferation. By binding to siRNA, p19 sequestrates these species and prevents them from interacting with the RNA-induced silencing complex (RISC), a protein complex that mediates the antiviral RNA silencing mechanism in the cell.
All these pathogens, now well identified in the Viral Envelope of SC2, have similar and almost always recurring correspondences, which unite them all, as if they belonged to a cleverly studied viral project, with a very specific purpose.
The pharmacological response in medical protocols, in response to SC2, should be very high but, on the contrary, there have been deficiencies in the use of unsuitable drugs, increasing lethality in the population.
For example, it is no coincidence that the understanding of the mechanism of action of bacterial lysates (specialties of medicines that contain bacterial antigens, i.e. fragments of bacteria, or polypeptide chains which, if taken by a healthy organism, should stimulate its immune response ) is the main cause of relapse in severe respiratory infections, such as acute pneumonia, and therefore its use should be prohibited.
In fact, inside the lysates there are endogenous microsomes with an active translocon complex (such as vesicular cellular artifacts derived from the fragmentation of the endoplasmic reticulum in the laboratory) which facilitate the incorporation of the bacterial channel of potassium KcsA (ion channels that allow the passage of cations of potassium through the plasma membrane of the cells), within the microsomal membranes themselves.
This would explain very well how, after the appearance of SC2, there was an exponential increase in the number of bacterial strains resistant to antibiotics, especially Gram negative.
SC2, due to its zoonotic / chimeric origin and its "parasitic nature", in addition to creating a very serious syndrome, which attacks both the vascular system and the immune system, binds and spreads mainly through bacterial, intestinal and external colonies to the guest.
For this reason, precisely due to the presence of the Viral Envelope present in SC2, all immunological control strategies of infectious diseases should be re-evaluated instantly.
