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.
Ribosomes are 2/3 RNA (a type of RNA known as ribosomal RNA or rRNA) and 1/3 protein. RNA is synthesized from viral DNA in an infected cell before protein synthesis begins. Some viruses, for example Tobacco Mosaic Virus (TMV) have RNA in place of DNA. If RNA extracted from a virus was injected into a host cell the cell began to make new viruses. Clearly RNA was involved in protein synthesis.
