Abstract

fetched live from OpenAlex

MUC1 mucin is expressed by normal human epithelial cells and is overproduced in underglycosylated form by malignant epithelial cells. A number of anticancer immunotherapeutic strategies are being designed with the goal of inducing humoral and cellular immune responses against MUC1 mucin. Newly synthesized MUC1 mucin is also expressed on polyclonally stimulated human T cells. An immunoregulatory role has been postulated for MUC1 mucin expressed by activated T cells. We now show that several MUC1 peptide and glycopeptide epitope specific antibodies bind to activated T cells and inhibit their proliferation. Inhibition by antibody B27.29 could be reversed by glycopeptide haptens specific for the antibody. Intact antibody B27.29 and its divalent F(ab')(2) fragment inhibited the proliferation of T cells undergoing T cell activation but the monovalent Fab' fragment did not, indicating that cross-linking of the MUC1 antigen on T cells is required for the inhibitory effect. MUC1 expression on activated T cells was increased in the presence of IL-12 but was not affected by IFN-gamma, IL-2, IL-4, IL-5, IL-10, IL-13 or TNF-alpha. Treatment of T cells inhibited by monoclonal antibody (MAb) B27.29 with either IL-2 or costimulatory anti-CD28 antibody restored proliferation to a level equivalent to that of control cultures. These results provide further support for the hypothesis that the expression of MUC1 on the activated T cell surface is associated with the regulation of T cell responses.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
