    摘要: An anti-CD2 monoclonal antibody according to the present invention can be: (1) a chimeric monoclonal antibody CD2 SFv-Ig produced by expression of the construct cloned in recombinant Escherichia coli culture ATCC No. 69277; (2) a monoclonal antibody having complementarity-determining regions identical with those of CD2 SFv-Ig; or (3) a monoclonal antibody competing with CD2 SFv-Ig for binding to CD2 antigen at least about 80% as effectively on a molar basis as CD2 SFv-Ig. Anti-CD2 monoclonal antibodies according to the present invention, as well as other antibodies that can modulate the interactions between T lymphocytes and monocytes, can be used to inhibit the production of HIV-1 by HIV-1-infected T cells in HIV-1-infected patients. In another use, T cells treated in vitro can be reinfused into AIDS patients to increase the proportion of functional, non-HIV-1-producing T cells in the patient.
