Abstract

The rat W3/25 antigen that appears to be equivalent to human CD4 (T4) antigen is expressed on thymocytes and T helper cells and plays a role in the response of T helper cells to antigen. The W3/25 and anti-T4 antibodies also label macrophages. In this paper we examine whether the macrophage antigen is the same as that on T cells. New monoclonal antibodies against the rat CD4 antigen, MRC OX-35 through OX-38, are described, all of which label peritoneal macrophages from normal and athymic rats. The molecular weight of W3/25 antigen on macrophages is indistinguishable from that on T cells. We conclude that macrophages express authentic CD4 (W3/25) antigen. Another new monoclonal antibody, MRC OX-34, labels an antigen of 50-54,000 mol wt that is expressed on rat T but not B cells or peritoneal macrophages. It was used to control for the presence of any T cell products in immunoprecipitation from rat macrophage extracts.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
