Abstract

Antigen presentation by MHC class I molecules, also referred to as cross-presentation, elicits cytotoxic immune responses. In particular, dendritic cells (DC) are the most proficient cross-presenting cells, since they have developed unique means to control phagocytic and degradative pathways.

This protocol allows the evaluation of antigen cross-presentation both in vitro (by using bone marrow-derived DC) and ex vivo (by purifying CD8+ DC from spleen after incorporation of particulate antigen) using ovalbumin (OVA)-coupled particles. Cross-presentation efficiency is measured by three different readouts: the B3Z hybridoma T cell line (Karttunen et al., 1992) and stimulation of antigen-specific CD8+ T cells (OT-I) (Kurts et al., 1996), either analyzing OT-I activation by CD69 expression or OT-I proliferation after labeling them with carboxyfluorescein succinimidyl ester (CFSE). By using this approach, we could show recently that DCs are able to increase cross-presentation efficiency transiently upon engagement of TLR4 (Alloatti et al., 2015).

Background

In mouse, antigen-presenting cells (APC) are able to take up exogenous antigens to process them and to load peptides derived from such exogenous antigens onto major histocompatibility complex (MHC) class I molecules. Peptide-MHC I complexes are subsequently transported to the plasma membrane, where they might be presented to CD8+ T cells thereby promoting T cell activation, a process referred to as cross-presentation (Joffre et al., 2012). Among the different APC, dendritic cells (DC) excel at cross-presentation and comprise of different subpopulations expressing the XCR1 marker, which have been shown to cross-present antigens very efficiently (i.e., CD8+ resident DC from spleen and CD103+ migratory DC from skin and lung) (Dorner et al., 2009; Crozat et al., 2011). While the purification of DC residing in spleen or migratory DC is feasible, it is laborious and expensive. In order to study the cell biology of DC, primary cultures of bone marrow-derived DC (BMDC) can be easily differentiated from myeloid progenitors by culturing them with GM-CSF. Even though BMDC cannot be associated with any particular DC subtype (perhaps inflammatory DC), they constitute a valuable tool to study the main characteristics of DC cell biology. Herein, we introduce a detailed protocol to analyze cross-presentation of particulate antigen by BMDC, but also by CD8+ splenic DC. Although previous protocols included different antigen forms and read-outs, the protocol described here aims to analyze cross-presentation in a comprehensive and concise way in different DC types.
