Interrogating Adaptive Immunity Using LCMV.

Interrogating Adaptive Immunity Using LCMV. Curr Protoc Immunol. 2020 09;130(1):e99 Authors: Dangi T, Chung YR, Palacio N, Penaloza-MacMaster P Abstract In this invited article, we explain technical aspects of the lymphocytic choriomeningitis virus (LCMV) system, providing an update of a prior contribution by Matthias von Herrath and J. Lindsay Whitton. We provide an explanation of the LCMV infection models, highlighting the importance of selecting an appropriate route and viral strain. We also describe how to quantify virus-specific immune responses, followed by an explanation of useful transgenic systems. Specifically, our article will focus on the following protocols. © 2020 Wiley Periodicals LLC. Basic Protocol 1: LCMV infection routes in mice Support Protocol 1: Preparation of LCMV stocks ASSAYS TO MEASURE LCMV TITERS Support Protocol 2: Plaque assay Support Protocol 3: Immunofluorescence focus assay (IFA) to measure LCMV titer MEASUREMENT OF T CELL AND B CELL RESPONSES TO LCMV INFECTION Basic Protocol 2: Triple tetramer staining for detection of LCMV-specific CD8 T cells Basic Protocol 3: Intracellular cytokine staining (ICS) for detection of LCMV-specific T cells Basic Protocol 4: Enumeration of direct ex vivo LCMV-specific antibody-secreting cells (ASC) Basic Protocol 5: Limiting dilution assay (LDA) for detection of LCMV-specific memory B cells Basic Protocol 6: ELISA for quantification of LCMV-specific IgG antibody Support...
