Modulation of the antigenicity of amylase in cervical glandular atypia, adenocarcinoma in situ and invasive adenocarcinoma.

Abstract

Using a polyclonal anti-salivary alpha-amylase antibody and a biotin-avidin-peroxidase detection system immunoreactive amylase was detected in 39/40 cases of invasive cervical adenocarcinoma, 6/7 cases of adenocarcinoma in situ, 6/6 cases of high-grade cervical glandular atypia and 12/14 cases of low-grade cervical glandular atypia. Expression was seen in only 2/18 normal endocervices and this was weak and patchy. In contrast, strong amylase activity was demonstrated in 18/18 normal endocervices using a starch film assay on frozen sections. It is proposed that antigenic modulation of amylase occurs during endocervical neoplastic transformation.

Antigenic Modulation

Antigenic modulation occurs when an antibody cross-links antigens on a cell surface, causing the antigens to become internalized. This can lead to therapeutic failure of monoclonal antibodies as the expression of the antigen becomes decreased on target cells. Find the latest research on antigenic modulation here.

Antibody Specificity

Antibodies produced by B cells are highly specific for antigen as a result of random gene recombination and somatic hypermutation and affinity maturation. As the main effector of the humoral immune system, antibodies can neutralize foreign cells. Find the latest research on antibody specificity here.
