Abstract

Lymphoid tissues are of intense interest for studies of the pathogenesis of human immunodeficiency virus (HIV) in humans and simian immunodeficiency virus (SIV) in macaques but are relatively difficult to sample non-invasively. Fine needle aspiration (FNA) cytology, conventionally a diagnostic procedure for lymphadenopathy, can be used for longitudinal study of tissue cell subsets during HIV/SIV infection. In this study, we serially sampled lymph node (LN) FNA from pigtail macaques and studied cell subsets in the aspect of absolute count, frequency, and functionality by flow cytometry. The median recovered lymphocyte count from FNA samples was 2.01×105 (3.0×103 to 2.25×106, n=38) and median ..
