Heart problems can cause sensations in other areas of the body besides your chest. Symptoms can include discomfort, pain, or pressure in the arms, back, neck, jaw, or stomach.
Infection with feline infectious peritonitis virus (FIPV), a feline coronavirus, frequently leads to death in spite of a strong humoral immune response. In previous work, we reported that infected monocytes, the in vivo target cells of FIPV, express viral proteins in their plasma membranes.These proteins are quickly internalized upon binding of antibodies.hese findings indicate that the viral antigen-antibody complexes were not internalized through any of the previously described pathways. Further characterization showed that this internalization process was independent from phosphatases and tyrosine kinases but did depend on serine/threonine kinases.
Function. The use of RNA in retroviruses is for the replication of the viral genome. The viruses use reverse transcriptase to create DNA in the cell's cytoplasm. The DNA is then incorporated into the host cell's nucleus and DNA.After the viral genes are incorporated into the host's DNA, the normal cell processes transcribe the protein's necessary for viral replication.he viruses use reverse transcriptase to create DNA in the cell's cytoplasm.
