Suppressor adherent phagocytic cells in solid tumors: a postulated escape mechanism

Medical Hypotheses
R C Parks


A localized graft-versus-host reaction was used to assess the cellular immunity of mice supporting progressive growth of an allogeneic tumor. It was found that early in tumor development anti-tumor-cellular-mediated immunity was hyper-responsive, and that adherent phagocytic cells isolated from the neoplasm would inhibit the specific immunological response. Based on these observations and indirect inference it was postulated that a major factor in the success of an immunogenic tumor is the coterminous development of a normal adherent phagocytic cell population which specifically nullifies, in situ, cellular-mediated anti-tumor immunity.

Adhesion Molecules in Health and Disease

Cell adhesion molecules are a subset of cell adhesion proteins located on the cell surface involved in binding with other cells or with the extracellular matrix in the process called cell adhesion. In essence, cell adhesion molecules help cells stick to each other and to their surroundings. Cell adhesion is a crucial component in maintaining tissue structure and function. Discover the latest research on adhesion molecule and their role in health and disease here.

Allogenic & Autologous Therapies

Allogenic therapies are generated in large batches from unrelated donor tissues such as bone marrow. In contrast, autologous therapies are manufactures as a single lot from the patient being treated. Here is the latest research on allogenic and autologous therapies.
