The non-vesicular (NV) fraction isolated from ER stressed cells activate dendritic cells (DCs) as bone fide DAMPs. (A) Schematic of the in vitro bone marrow-derived dendritic cell (BMDC or simply DC) maturation protocol. (B) Macrophage and dendritic cell markers in control and DAMP treated BMDCs. Lipopolysaccharide (LPS) was used as a positive control. (C,D) Dendritic cell markers CD40 and CD86 after treatment with indicated compounds. Data are the mean ± stdv from three separate determinations. (E,F) IL-6 cytokine production after treatment with the indicated compounds. (G,H) TNF-α production after treatment with the indicated compounds.
