The impact of spleen tyrosine kinase (Syk) signaling might be prominent in lupus because (i) Syk is a shared downstream signaling molecule among circulating immune complex, LPS, and (1→3)-β-D-glucan (BG), and (ii) all of these factors are detectable in the serum of Fc gamma receptor IIb-deficient (FcgRIIb-/-) mice with sepsis. Syk inhibition downregulated several inflammatory pathways in FcgRIIb-/- macrophages activated with BG + LPS suggesting the potential anti-inflammatory impact of Syk inhibitors in lupus.

Piperonyl acetone is a food additive used in edible seasonings.

Methylene Violet 3RAX, a phenazine dye, is utilized for staining cell mitochondria and has the capability to alter DNA's molecular structure, disrupt DNA modules, and promote reactive singlet oxygen generation.
