Simultaneous and independent use of cocaine and alcohol by heroin addicts was shown to variably modulate the ability of their T cells to form E-rosettes with sheep erythrocytes (E). As reported previously, the percentages of E-rosette-forming T cells of both active and total types were depressed in association with heroin addiction. We show here that the kinetic curve of the rate of E-rosette formation is also depressed by heroin use and that the use of cocaine but not alcohol by heroin addicts reverses depression of E-rosette formation by heroin. The percentages of E-rosette-forming T cells from the bloods of heroin addicts who used both alcohol and cocaine, as well as the kinetic rate curves of E-rosette formation, were intermediate between the essentially normal levels found for heroin addicts who used cocaine and the severely depressed levels evident for users of heroin alone or heroin plus alcohol. Modulation of the levels of E-rosette formation by alcohol used in conjunction with cocaine and/or heroin was variably dose dependent. Polydrug effects evident by analyses of E-rosette formation were not seen when the percentages of lymphocytes reactive with LYT-3 (anti-E-receptor, 9.6 epitope) and OKT-3 (anti-total T cell) monoclonal antibodies were assessed cytofluorometrically, although the data suggested that subnormal percentages of LYT-3+ T cells were present when heroin addicts also used cocaine. These findings are relevant to basic understanding of T-cell physiology from a neuroimmunological perspective and also suggest ways that addictive drugs may modulate the immunocompetence of drug addicts.
