Here we describe a whole-mount fluorescent in situ hybridization (FISH) protocol for determining the expression and localization properties of RNAs expressed during embryogenesis in the fruit fly, Drosophila melanogaster.

Unlike cell-free HIV-1 particles, infected CD4⁺ T cells are effectively sensed by plasmacytoid dendritic cells (pDCs). This manuscript describes a method where peripheral blood mononuclear cells (PBMCs) or isolated pDCs are co-cultured with HIV-1 infected T cells to evaluate innate sensing by pDCs as assessed by release of type-I IFN.

¹Centre de Recherche du Centre hospitalier de l'Université de Montréal (CRCHUM), ²Institut de Recherches Cliniques de Montréal (IRCM), ³Département de médecine, Faculté de médecine, Université de Montréal

Here, we present a tool that can be used to study the posttranscriptional modulation of a transcript in primary alveolar epithelial cells by using an inducible expression system coupled to a pipette electroporation technique.
