That reaction results when a localized accumulation of immune complexes — antibodies bound to their antigens — is deposited in tissue and sets off an inflammatory response involving the infiltration and activation of immune cells, initially the neutrophil.

Since a primary function of the dendritic cells is to present an antigen to T - cells, to activate the T - cells and begin the immune response, the researchers suspected that T - cell activation in the heart tissue, and perhaps heart - tissue injury caused by T - cells, might be central to the pathological heart enlargement that is called remodeling.
