Consistent results have not been obtained yet on the presence of antibody to the M protein of measles virus in the sera of patients with subacute sclerosing panencephalitis (SSPE). We performed a comparative study on various immunoprecipitation systems which appeared in the literature and found that
The F glycoprotein of paramyxoviruses is responsible for cell fusion and hemolysis and for virus penetration via fusion of viral and cell membranes. These functions are activated by specific proteolytic cleavage of an inactive precursor (F0) into two disulfide-linked polypeptides (F1 and F2). The
Differential expression of the amyloid precursor protein gene (APP) may be important in the development of amyloidosis in Alzheimer's disease (AD) and experimentally in the brain's response to injury. Controversial data suggests that APP isoforms containing the Kunitz protease inhibitor isoform (APP
Enzyme treatment (protease or trypsin) was applied to formalin-fixed paraffin-embedded materials and virus-infected cultured cells to detect viral antigens by immunofluorescence. The viral antigens were demonstrated in several organs of autopsy or biopsy cases of which diagnoses had been established
