- The term ‘cell-bound antibody’ is used here to describe substances which at the time of testing were associated with blood leucocytes and enabled these cells to react specifically with the homologous antigen.

any antibody molecule that is bound to the surface of a cell, e.g. an incomplete antibody(def. 1) or a cytophilic antibody.
Jun 23, 2022 · Within the boundaries of the system, cells generate a diverse repertoire of surface antibodies (B-cell receptors, BCR) that allows them to probe the complete antigen landscape or antigenome. In fact, BCRs are probing not whole molecules but rather patches of molecular surfaces called epitopes.

A plasma cell is an immune cell that secrets antibodies; these cells arise from B cells that were stimulated by antigens. Similar to T cells, naïve B cells initially are coated in thousands of B cell receptors (BCRs), which are membrane-bound forms of Ig (immunoglobulin, or an antibody).
Engagement of basophil-bound IgD by antigen would then trigger basophil release of IL-4, which may amplify humoral immunity by enhancing B cell production of IgG. This antibody is abundantly produced in human nasopharyngeal cavities and may cooperate with IgD to provide local immune protection.
