We used a sensitive method based on tetramers of peptide and major histocompatibility complex II (pMHCII) to determine whether CD4(+) memory T cells resemble the T helper type 1 (T(H)1) and interleukin 17 (IL-17)-producing T helper (T(H)17) subsets described in vitro. Intravenous or intranasal infection with Listeria monocytogenes induced pMHCII-specific(More)
Group A streptococcus (GAS, Streptococcus pyogenes) is the cause of a variety of clinical conditions, ranging from pharyngitis to autoimmune disease. Peptide-major histocompatibility complex class II (pMHCII) tetramers have recently emerged as a highly sensitive means to quantify pMHCII-specific CD4+ helper T cells and evaluate their contribution to both(More)
The invention of peptide-MHC-tetramer technology to label antigen-specific T cells has led to an enhanced understanding of T lymphocyte biology. Here we describe the development of an in situ pMHC-II tetramer staining method to visualize antigen-specific CD4+ T cells in tissues. This method complements other methods developed that similarly use MHC class II(More)
