The interplay of dendritic cell subsets in systemic lupus erythematosus
Lupus Erythematosus, Systemic
Dendritic cells (DC) control immunity and tolerance. Hence, we surmised that systemic lupus erythematosus (SLE), a systemic autoimmune disease with autoreactive T and B cells, might be due to DC alterations. Based on our findings, we are proposing a model of SLE where autoimmune responses are driven by unabated activation of myeloid DC through IFN-alpha produced by plasmacytoid DC. Thus, interplay between DC subsets might represent a key component of SLE pathogenesis.
