AB Creutzfeldt-Jakob disease (CJD) is the most common spongiform encephalopathy affecting humans. Prion protein (PrP) immunohistochemistry may be useful for studying the localization of prion protein and assessing its role in CJD, the accumulation of a specific protease resistant PrP isoform being apparently pathognomic to the spongiform encephalopathies. However, a number of factors influence the results of immunostaining, making interpretation and comparisons between the staining of different PrP antisera difficult. This study has examined qualitatively and quantitatively the staining produced by four antisera raised to a variety of prion protein homologues in two cases of CJD and two age-matched controls. Quantitative analysis was provided through the use of custom designed image analysis software. Kuru, granular and multicentric plaques, cellular, perivacuolar and white matter PrP deposits were observed in CJD cases with all four antisera. No significant immunostaining was seen in the control tissue. Some antibody specific staining patterns were observed qualitatively; however, quantitative analysis showed statistically significant correlations between all the antisera on the diseased brain tissue. Prion protein immunohistochemistry is thus useful in interpreting patterns of protein distribution in diseased brain but care may be required in interpreting the results of a single antibody.
