 AB    Human immunodeficiency virus (HIV) infection is initiated by attachment
       of the virus to specific target cells. An octapeptide sequence contained
       within the envelope of HIV, peptide T, mediates the viral binding. Since
       there is an appreciable structural similarity between peptide T and an
       eight amino acid sequence of VIP, it is interesting to investigate the
       interaction of peptide T with the VIP receptor-effector system of
       immunocompetent cells from both rat and mouse. In this paper, we show
       the lack of interaction between peptide T and VIP receptor-effector
       system in peripheral blood lymphocytes, spleen lymphocytes and
       macrophages of rat and in macrophages of mouse. These results do not
       support the hypothesis that HIV through peptide T may interact with the
       VIP receptor-effector system present in immunocompetent cells.
