    • Introduction

      A human infecting coronavirus (viral pneumonia) called 2019 novel coronavirus, 2019-nCoV was found in the fish market at the city of Wuhan, Hubei province of China on December 2019.

      The 2019-nCoV shares an 87% identity to the 2 bat-derived severe acute respiratory syndrome 2018 SARS-CoV-2 located in Zhoushan of eastern China. 2019-nCoV has an analogous receptor-BD-structure to that of 2018 SARS-CoV, even though there is a.a. diversity so thus the 2019-nCoV might bind to ACE2 receptor protein (angiotensin-converting enzyme 2) in humans.

      While bats are possibly the host of 2019-nCoV, researchers suspect that animal from the ocean sold at the seafood market was an intermediate host. RSCU analysis proposes that the 2019-nCoV is a recombinant within the viral spike glycoprotein between the bat coronavirus and an unknown coronavirus.

    • Physical Appearance

    • Introduction

      Sarcoglycan Delta (SGCD) is one of the four known components of the sarcoglycan complex, which is a subcomplex of the dystrophin-glycoprotein complex (DGC) and is expressed mainly in skeletal and cardiac muscle. DGC forms a link between the F-actin cytoskeleton and the extracellular matrix. SGCD protein’s mutations have been associated with autosomal recessive limb-girdle muscular dystrophy and dilated cardiomyopathy. SGCD gene expression is regulated by MITF In melanocytic cells.

    • Introduction

      H1N1 is a subtype specie of Influenza A virus. H1N1 Influenza Virus has mutated into various strains such as the Spanish Flustrain, mild humanflu strains, endemic pigstrains, and various strains found in birds. The Influenza A Virus is a globular particle about 100nm in diameter, sheathed in a lipid bilayer derived from the plasma membrane of its host. Studded in the lipid bilayer are two integral membrane proteins some 500 molecules of hemagglutinin ("H") and some 100 molecules of neuraminidase ("N"). Within the lipid bilayer are 3000 molecules of matrix protein and 8 pieces of RNA. Each of the 8 RNA molecules is associated with many copies of a nucleoprotein, several molecules of the three subunits of its RNA polymerase some "non-structural" protein molecules of uncertain function.

    • Introduction

      A human infecting coronavirus (viral pneumonia) called 2019 novel coronavirus, 2019-nCoV was found in the fish market at the city of Wuhan, Hubei province of China on December 2019.The 2019-nCoV shares an 87% identity to the 2 bat-derived severe acute respiratory syndrome 2018 SARS-CoV-2 located in Zhoushan of eastern China. 2019-nCoV has an analogous receptor-BD-structure to that of 2018 SARS-CoV, even though there is a.a. diversity so thus the 2019-nCoV might bind to ACE2 receptor protein (angiotensin-converting enzyme 2) in humans.While bats are probably the host of 2019-nCoV, researchers suspect that animal from the ocean sold at the seafood market was an intermediate host. RSCU analysis proposes that the 2019-nCoV is a recombinant within the viral spike glycoprotein between the bat coronavirus and an unknown coronavirus.

    • Introduction

      Human T-lymphotropic virus (HTLV) is a human, single-stranded RNA retrovirus that causes T-cell leukemia and T-cell lymphoma. The virus activates a subset of T-helper cellscalled Th1cells. The result is a proliferation of Th1 cells and overproduction of Th1 related cytokines (mainly IFN-gamma and TNF-alpha). Feedback mechanisms of these cytokines cause a suppression of the Th2 lymphocytes and a reduction of Th2 cytokine production (mainly IL-4, IL-5, IL-10 and IL-13). The end result is a reduction in the ability of the infected host to mount an adequate immune response to invading organisms that require a predominantly Th2 dependant response (these include parasitic infections and production of mucosal and humoral antibodies).

    • Stability

      HTLV-1 Mosaic although stable at 4°C for 1 week, should be stored below -18°C. Please prevent freeze thaw cycles.

    • Applications

      HTLV-1 Mosaic can be used as an antigen in ELISA and Western Blots. Excellent reagent for correct detection of HTLV infections, with minimal specificity problems.

    • Introduction

      SARS Coronavirus is an enveloped virus containing three outer structural proteins, namely the membrane (M), envelope (E), and spike (S) proteins. Spike (S)-glycoprotein of the virus interacts with a cellular receptor and mediates membrane fusion to allow viral entry into susceptible target cells. Accordingly, S-protein plays an important role in virus infection cycle and is the primary target of neutralizing antibodies.It has recently been shown that SARS is caused by a human coronavirus. Human coronaviruses are the major cause of upper respiratory tract illness in humans, such as the common cold. Coronaviruses are positive-stranded RNA viruses, featuring the largest viral RNA genomes known to date (27-31 kb). The first step in coronavirus infection is binding of the viral spike protein, a 139-kDa protein, to certain receptors on host cells. The spike protein is the main surface antigen of the coronavirus. The most prominent protein in the culture supernatants infected with SARS virus is a 46 kDa nucleocapsid protein. This suggests that the nucleocapsid protein is a major immunogen that may be useful for early diagnostics.

    • Introduction

      The life cycle of Toxoplasma gondii has two phases. The coccidia like takes place only in members of the Felidae family which makes these animals the parasite's primary host. The asexual part of the life cycle can take place in any warm-blooded animal, like other mammals(including felines) and birds. T. gondii constructing daughter scaffolds within the mother cell. In the intermediate hosts (including felines), the parasite invades cells, forming intracellular so-called parasitophorous vacuoles containing bradyzoites, the slowly replicating form of the parasit. Vacuoles form tissue cysts mainly within the muscles and brain. Since they are within cells, the host's immune system does not detect these cysts. Resistance to antibiotics varies, but the cysts are very difficult to eradicate entirely. Within these vacuoles T. gondii propagates by a series of binary fissions until the infected cell eventually bursts and tachyzoites are released. Tachyzoites are the motile, asexually reproducing form of the parasite. Unlike the bradyzoites, the free tachyzoites are usually efficiently cleared by the host's immune response, although some manage to infect cells and form bradyzoites, thus maintaining the infection.

    • Introduction

      Entry of HSV into the host cell involves interactions of several viral glycoproteins with cell surface receptors. The virus particle is covered by an envelope which, when bound to specific receptors on the cell surface, will fuse with the cell membrane and create an opening, or pore, through which the virus enters the host cell. The sequential stages of HSV entry are analagous to those of other viruses. At first, complementary receptors on the virus and cell surface bring the two membranes into proximity. In an intermediate state, the two membranes begin to merge, forming a hemifusion state. Finally, a stable entry pore is formed through which the viral envelope contents are introduced to the host cell.

    • Background

      Severe acute respiratory syndrome coronavirus (SARS-CoV) and Middle East respiratory syndrome coronavirus (MERS-CoV) have caused significant outbreaks with severe respiratory illness in recent years. The spike proteins of these viruses play a crucial role in viral entry and host cell recognition. This research aims to explore the structure, function, and implications of SARS and MERS spike proteins in viral pathogenesis and the development of therapeutic interventions. Understanding the mechanisms of viral entry can provide valuable insights into the design of effective antiviral strategies.

      Structure and Function of SARS and MERS Spike Proteins:

      The spike proteins of SARS-CoV and MERS-CoV are trimeric glycoproteins located on the viral surface. They consist of S1 and S2 subunits, with the S1 subunit responsible for receptor binding and the S2 subunit involved in membrane fusion. The spike proteins contain key domains, including the receptor-binding domain (RBD) and the fusion peptide, which mediate the interactions with host cell receptors and membrane fusion during viral entry.

      Interaction with Host Cell Receptors:

      The SARS-CoV spike protein primarily interacts with the angiotensin-converting enzyme 2 (ACE2) receptor, which is expressed in various tissues, including the respiratory tract. The binding of the SARS-CoV spike protein to ACE2 is crucial for viral entry into host cells. Similarly, the MERS-CoV spike protein interacts with the dipeptidyl peptidase 4 (DPP4) receptor, which is predominantly expressed in the lungs and other tissues. These receptor interactions determine the host range and tissue tropism of the viruses.

      Implications for Viral Pathogenesis:

      The interaction between the spike proteins of SARS-CoV and MERS-CoV and their respective receptors initiates a cascade of events leading to viral entry and replication. The binding of the spike protein to the receptor triggers conformational changes that expose the fusion peptide, facilitating membrane fusion and viral entry into host cells. The specificity and affinity of the spike-receptor interaction play a critical role in determining viral tropism, disease severity, and transmission dynamics.

      Therapeutic Strategies Targeting Spike Proteins:

      The spike proteins of SARS-CoV and MERS-CoV present attractive targets for the development of antiviral interventions. Various approaches have been explored, including the development of neutralizing antibodies that specifically target the spike proteins and inhibit viral entry. Additionally, small molecule inhibitors and peptide-based therapeutics are being investigated to disrupt the spike-receptor interaction and block viral entry. Vaccine development efforts have also focused on generating immune responses against the spike proteins to prevent infection.

      Challenges and Future Directions:

      Although significant progress has been made in understanding the structure and function of SARS and MERS spike proteins, several challenges remain. The emergence of novel coronavirus variants necessitates continuous surveillance and adaptation of therapeutic strategies. Additionally, potential cross-reactivity and immunogenicity concerns need to be addressed to ensure the safety and efficacy of spike protein-based therapeutics.

      Conclusion:

      The study of SARS and MERS spike proteins provides valuable insights into the mechanisms of viral entry and pathogenesis. Understanding the interactions between spike proteins and host cell receptors is crucial for the development of effective antiviral strategies. Further research on spike protein structure, receptor binding, and fusion mechanisms is essential to combat current and future coronavirus outbreaks. By unraveling the complexities of viral entry, we can pave the way for the development of novel therapeutics to mitigate the impact of SARS-CoV, MERS-CoV, and related coronaviruses.

    • Introduction

      A human infecting coronavirus (viral pneumonia) called 2019 novel coronavirus, 2019-nCoV was found in the fish market at the city of Wuhan, Hubei province of China on December 2019.

      The 2019-nCoV shares an 87% identity to the 2 bat-derived severe acute respiratory syndrome 2018 SARS-CoV-2 located in Zhoushan of eastern China. 2019-nCoV has an analogous receptor-BD-structure to that of 2018 SARS-CoV, even though there is a.a. diversity so thus the 2019-nCoV might bind to ACE2 receptor protein (angiotensin-converting enzyme 2) in humans.

      While bats are possibly the host of 2019-nCoV, researchers suspect that animal from the ocean sold at the seafood market was an intermediate host. RSCU analysis proposes that the 2019-nCoV is a recombinant within the viral spike glycoprotein between the bat coronavirus and an unknown coronavirus.

      Plasmodium falciparum is a protozoan parasite, one of the species of Plasmodium that cause malaria. Malaria parasites are members of the Apicomplexa. Apicomplexa are characterized by a set of organelles found in some stages of the parasite's life cycle. These organelles, collectively known as apical organelles because of their localization at one end of the parasite, are involved in interactions between the parasite and host. In particular, the apical organelles have been implicated in the process of host cell invasion. In the case of Plasmodium, three distinct invasive forms have been identified: sporozoite, merozoite, and ookinete.
