Abstract Systemic lupus erythematosus (SLE) patients are photosensitive, where ultraviolet radiation (UVR) exposure can induce skin inflammation and also trigger systemic disease flares. The link between photosensitive autoimmunity is not well understood. Skin communicates with the immune system via lymphatic vessels that carry lymph into conduit of nodes (LNs), which ensheathed by fibroblastic...
Previous studies attempting to influence the severity of collagen-induced arthritis (CIA) by modulating the LIGHT (lymphotoxin-related inducible ligand that competes for glycoprotein D binding to herpesvirus entry mediator (HVEM) on T cells)/lymphotoxin pathway have yielded conflicting results. To further clarify the role of LIGHT in autoimmune arthritis, a HVEM-Ig fusion protein was used. CIA ...
T memory cells specifically responsive to ovalbumin and performing the diverse functions of DNA synthesis, lymphotoxin release, and regulation can be isolated in enriched numbers in the most buoyant fractions (A+B) of bovine serum albumin gradients on day 9 after sensitization. At least 20-30% of these cells are capable of mounting a blastogenic response to ovalbumin. A+B cells responding to ov...
Recent studies revealed that the lymphotoxin/lymphotoxin beta receptor (LT)/ LT R system activates the noncanonical nuclear factor– B (NFB) signaling pathway involving I kappa B kinase 1/I kappa B kinase (IKK1/IKK ) and NFB–inducing kinase (NIK) to direct processing of the nf b2 protein p100 to yield RelB:p52 complexes. Despite the biochemical evidence, LT-, RelB-, p52-deficient mice show discr...
Our previous studies indicated that lymphotoxin β receptor (LTβR) activation controls and downregulates inflammatory reactions. In this study, we report that LTβR activation on primary mouse macrophages results in induction of tripartite motif containing (TRIM) 30α, which negatively regulates NF-κB activation induced by TLR signaling. LTβR activation results in a downregulation of proinflammato...
Microenvironment and activation signals likely imprint heterogeneity in the lymphatic endothelial cell (LEC) population. Particularly LECs of secondary lymphoid organs are exposed to different cell types and immune stimuli. However, our understanding of the nature of LEC activation signals and their cell source within the secondary lymphoid organ in the steady state remains incomplete. Here we ...
Although the essential role of tumor necrosis factor (TNF) in resistance to Listeria monocytogenes infection is well established, the roles of the related cytokines lymphotoxin alpha (LTalpha) and lymphotoxin beta (LTbeta) are unknown. Using C57BL/6 mice in which the genes for these cytokines were disrupted, we examined the contributions of TNF, LTalpha, and LTbeta in the host response to Liste...
