Many immunological processes are contextually controlled by complex interactions among different cell types. Several studies have shown that B cells produce the immune regulatory cytokine IL-10 in response to different external stimuli but also to immune-mediated signals. Endogenous signals that derive from the cross talk between B lymphocytes and other cells of the immune system can affect IL-10 production by B cells in both physiological and pathological conditions. With the aim to provide a guide for the study of how partner cells can induce IL-10-producing B cells, here we describe the protocols to investigate IL-10 production at a single cell level in a dendritic cell-B cell coculture in vitro system. These methods are a proof of concept that can be easily extrapolated and adapted to the study of the interaction between B cells and other immune cell types.

Abstract
Many immunological processes are contextually controlled by complex interactions among different cell types. Several studies have shown that B cells produce the immune regulatory cytokine IL-10 in response to different external stimuli but also to immune-mediated signals. Endogenous signals that derive from the cross talk between B lymphocytes and other cells of the immune system can affect IL-10 production by B cells in both physiological and pathological conditions. With the aim to provide a guide for the study of how partner cells can induce IL-10-producing B cells, here we describe the protocols to investigate IL-10 production at a single cell level in a dendritic cell-B cell coculture in vitro system. These methods are a proof of concept that can be easily extrapolated and adapted to the study of the interaction between B cells and other immune cell types.File | Dimensione | Formato | |
