(Submitter supplied) Atherosclerosis is a transmural chronic inflammatory condition of small and large arteries that is associated with adaptive immune responses at all disease stages. However, impacts of adaptive immune reactions on clinically apparent atherosclerosis such as intima lesion (plaque) rupture, thrombosis, myocardial infarction, and aneurysm largely remain to be identified. It is increasingly recognized that leukocyte infiltrates in plaque, media, and adventitia are distinct but their specific roles have not been defined. more...

(Submitter supplied) Mouse aorta smooth muscle cells (SMCs) express TNF receptor superfamily member 1A (TNFR1) and lymphotoxin ß receptor (LTßR). Circumstantial evidence has linked the SMC LTßR to tertiary lymphoid organogenesis in diseased aortae of hyperlipidemic mice. Here, we explored potential roles of TNFR1 and LTßR activation in cultured SMCs. TNFR1 signaling by TNF activated the classical RelA NF-κB pathway, whereas LTßR signaling by agonistic anti LTßR antibody activated both the classical RelA and alternative RelB NF-κB pathways. more...

(Submitter supplied) We previously observed that formation of aorta and innominate artery atherosclerotic lesions in the intima of hyperlipidemic apoE-deficient mice but not wild-type mice was accompanied by a marked age-dependent adventitial T cell infiltration. As the mice aged, adventitial T cells formed T/T cell-, T/B cell-, and T/B/dendritic cell aggregates adjacent to atherosclerotic lesions. Some of the adventitial infiltrates formed large clusters of various immune cells including T cells, B cells (centrocytes, follicular mantle cells), dendritic cells, follicular dendritic cells, and plasma cells with preferential formation in the suprarenal portion of the abdominal aorta. more...

(Submitter supplied) Background: Lymphotoxin signaling via the lymphotoxin-β receptor (LTβR) has been implicated in several biological processes, ranging from development of secondary lymphoid organs, maintenance of splenic tissue, host defense against pathogens, autoimmunity, and lipid homeostasis. The major transcription factor that is activated by LTβR crosslinking is NF-κB. Two signaling pathways have been described that result in the activation of classical p50-RelA and alternative p52-RelB NF-κB heterodimers. more...

(Submitter supplied) To investigate the regulatory mechanisms and targets of the activation of NF-kB and inflammatory pathways, we treated HPV(-) head and neck cancer line UM-SCC 46 cells with TNFα and LTβ at different time points, and compared the gene expression by microarray. TNFα uniquely induced 172 genes, LTβ specifically induced 202 genes, while 155 genes were induced by both ligands. Total RNA samples were isolated from UM-SCC 46 cells after TNFα or LTβ treatment at different time points, and the gene expression were compared with untreated cell controls.

Here, we explored artery TLOs (ATLOs) to delineate atherosclerosis T cell responses in apoe-/- mice during aging. Though the T cell repertoire showed systemic age-associated contractions in size and modifications in subtype composition and activation, wt and apoe-/- mice were equally affected. more...

(Submitter supplied) Developmental signals are known to modulate inflammation. How ever, the mechanistic insight that links developmental and inflammatory signaling remains elusive. In the current study, we identifya critical role of NF-kB system in mediating stimulus specific crosstalk that allows developmental LTbR signals to sustain inflammatory TLR4 induced RelA/NF-kB response and gene expression. LTbR activated non-canonical signaling targets canonical TLR4 induced, nfkb2 encoded p100 not only to deplete inhibitory IkBd/(p100)2, but also to supplement RelA:p52/NF-kB dimers. more...

(Submitter supplied) Stringent regulation of TNF signaling prevents aberrant inflammation. TNF engages the canonical NF-kB pathway for activating the RelA:p50 heterodimer, which mediates specific expressions of pro-inflammatory and immune response genes. Importantly, the NF-kB system discriminates between time-varied TNF inputs. Negative feedback regulators of the canonical pathway, including IkBa, thought to ensure transient RelA:p50 responses to brief TNF stimulations. more...

(Submitter supplied) As a specialized subset of intestinal epithelial cells (IECs), goblet cells (GCs) play an important role during the antibacterial response via mucin production. However, the regulatory mechanisms involved in GC differentiation and function during infection, particularly the role of immune cell-IEC crosstalk, remain largely unknown. Here, using VillinΔLtbr conditional knockout mice, we demonstrate that LTβR, expressed on IECs, is required for GC hyperplasia and mucin 2 (MUC2) expression during Listeria infection for host defense but not homeostatic maintenance in the naïve state. more...

(Submitter supplied) While activation of canonical NF-κB signaling through the IKK complex is well studied, few regulators of NIK-dependent non-canonical p52 nuclear translocation have been identified. We discovered a novel role for cyclin dependent kinase 12 (CDK12) in transcriptionally regulating the non-canonical NF-κB pathway. High-content phenotypic screening identified a novel compound, 919278, which inhibits lymphotoxin β receptor (LTβR)- and FN14-dependent p52 nuclear translocation, but not TNFα receptor (TNFR)-mediated, canonical NF-κB p65 nuclear translocation. more...

(Submitter supplied) How LTβR-signalling drives chronic tissue damage particularly in the lung, which mechanisms regulate this process, and whether LTβR-blockade might be of therapeutic value has remained unclear. To study the mechanisms underlying LTβR-inhibition, a transcriptional analysis was performed on lung tissue from B6 mice exposed to cigarette smoke for 6 months and treated therapeutically with LTβR-Ig from 4 to 6 months compared to mice exposed to cigarette smoke for 6 months and treated with control Ig from 4 to 6 months and filtered air control. more...

(Submitter supplied) Lymphotoxin β-receptor-signalling orchestrates lymphoid neogenesis and subsequent tertiary lymphoid structures (TLS) associated with severe chronic inflammatory diseases spanning multiple organ systems. How LTβR-signalling drives chronic tissue damage particularly in the lung, which mechanism(s) regulate this process, and whether LTβR-blockade might be of therapeutic value has remained unclear. Here we demonstrate increased lymphotoxin expression of LTbR-ligands on myeloid and adaptive and innate immune-cells, enhanced non-canonical NF-κB signalling and enrichment of LTβR-target gene expression in epithelial cells of lungs from patients and mice with smoking-associated chronic obstructive pulmonary disease (COPD). more...
