Alongside their potential role in modulating autoimmunity, the draining LNs may be also critically associated with the severity of joint involvement.
Both sex steroid estrogen and pituitary hormones such as prolactin are known to modulate autoimmunity and are thus supposed to play a role in SLE.
For example, there is great interest in mesenchymal stromal cells and the possibility that they could modulate autoimmunity or somehow promote islet cell regeneration [ 6].
Chloroquine is no TLR9 specific antagonist, however, and may interfere with other endosome-dependent disease mechanisms, for example, TLR7-dependent ssRNA recognition [ 90, 91] In view of the aforementioned potential of microbial molecules to trigger or modulate autoimmunity, new hypotheses arise that may influence the management of patients with autoimmune disease.
Previous findings have reported an exacerbated disease phenotype and enhanced mortality in IL10 gene-deficient lupus-prone MLR mice, and administration of rIL-10 reduced autoantibody production, highlighting the importance of IL10 in down modulating autoimmunity (Yin et al., 2002).
These changes sensitize β-cells to proapoptotic signals (e.g., cytokines), modulating apoptosis in preclinical T1D autoimmunity.
Antigen-specific immunotherapies have proved to be highly specific in modulating B-cell autoimmunity, mainly by inducing regulatory responses, while non-antigen-specific interventions mediate protection by clonal deletion/anergy in activated (pathogenic) T cells, with subsequent differentiation and expansion of Tregs.
This effect is sustained for at least 6 months, and may modulate protective autoimmunity.
Commensal microbiota may initiate autoimmunity in SS and SLE.
For many years, rheumatoid factor was the only evidence for autoimmunity in RA.
