The authors propose that patients with SLE have a higher frequency of NET-specific B cells in the B cell memory pool than healthy patients. However, they also note that patients with SLE may have a genetically determined tendency towards increased B cell activation. The study did not determine whether in vivo B cell activation required direct interaction with NETting neutrophils. Nevertheless, the authors suggest NETs or the LL37-DNA complexes may serve as targets for SLE therapy.
