using immunohistochemical tests and monoclonal antibodies specific for phosphorylated isoforms of the high-molecular-weight human neurofilament subunit ( nf-h ) or for nonphosphorylated isoforms of nf-h and the middle-molecular-weight nf protein , we detected phosphorylated and nonphosphorylated nf protein isoforms in typical central bronchial carcinoids but not in atypical or peripheral carcinoids or in small cell undifferentiated carcinomas of the lung .
