IL-12 Virotherapy Induces Immune Equilibrium in Melanoma That is Overcome by Blockade of Innate Inflammatory Cytokine

ABSTRACT: Viral vectors deliver therapeutic cargo with the natural adjuvant effect of a pathogen. We engineered a non-replicating herpes simplex virus 1, d106S-IL12, to deliver IL-12 to the tumor microenvironment, resulting in a type I interferon response, rapid production of T cell recruiting chemokines, and accumulation of melanoma-specific CD8 T cells. We immunologically defined a long-term, stable immune equilibrium, whereby mice neither succumbed nor fully cleared their tumors. We profiled the immune equilibrium induced by d106S-IL12, identifying blockade of innate inflammatory cytokines, TNFα, IL-1β, or IL-6 as possible synergistic interventions. Single-cell RNA-sequencing demonstrated that d106S-IL12 induced a loss of Tregs and a shift towards Th1 responses, while blockade of inflammatory cytokines repolarized macrophages towards a less suppressive phenotype. Blockade of each cytokine resulted in downregulation of overlapping inflammatory pathways, shifting immune equilibrium towards tumor clearance. These results suggest targeting innate inflammatory cytokines could enhance immunotherapy efficacy while potentially mitigating toxicity.

Proteomic analysis of human eosinophils stimulated with IL-4 and IL-5

Project description:Activated eosinophils is a major cell type to be involved in allergic diseases. Type 2 cytokines (IL-4 and IL-5) are important to establish and augment their inflammatory process. The aim of this study is to clarify the role of these cytokines as direct activators for human eosinophils.

Phosphoproteomic analysis of IL-2 MSA and IL-12 MSA combination on T cell signaling

Project description:Engineered cytokine-based approaches for immunotherapy of cancer are poised to enter the clinic, with IL-12 being at the forefront. However, little is known about potential mechanisms of resistance to cytokine therapies. We found that orthotopic murine lung tumors were resistant to systemically delivered IL-12 fused to murine serum albumin (MSA, IL12-MSA) due to low IL-12R expression on tumor-reactive CD8+ T cells. IL2-MSA increased binding of IL12-MSA by tumor-reactive CD8+ T cells, and combined administration of IL12-MSA and IL2-MSA led to enhanced tumor-reactive CD8+ T cell effector differentiation, decreased numbers of tumor-infiltrating CD4+ regulatory T (Treg) cells, and increased survival of lung tumor-bearing mice. Predictably, the combination of IL-2 and IL-12 at therapeutic doses led to significant dose-limiting toxicity. Administering IL-12 and IL-2 analogs with preferential binding to cells expressing IL12rb1 and CD25, respectively, led to a significant extension of survival in mice with lung tumors while abrogating dose-limiting toxicity. These findings suggest that IL-12 and IL-2 represent a rational approach to combination cytokine therapy whose dose-limiting toxicity can be overcome with engineered cytokine variants.

TREM-1 is a novel therapeutic target in Psoriasis

Project description:Our group recently described a population of antigen presenting cells that appear to be critical in psoriasis pathogenesis, termed inflammatory myeloid dendritic cells (CD11c+ BDCA1-). Triggering receptor expressed on myeloid cells type-1 (TREM-1) signaling was a major canonical pathway in the published transcriptome of these cells. TREM-1 is a member of the immunoglobulin superfamily, active through the DAP12 signaling pathway, with an unknown ligand. Activation through TREM-1 induces inflammatory cytokines including IL-8, MCP/CCL2 and TNF. We now show that TREM-1 was expressed in the skin of healthy and psoriatic patients, and there was increased soluble TREM-1 in the circulation of psoriasis patients. In psoriasis lesions, TREM-1 was co-localized with dendritic cells as well as CD31+ endothelial cells. TREM-1 expression was reduced with successful NB-UVB, etanercept and anti-IL-17 treatments. An in vitro model of PGN-activated monocytes as inflammatory myeloid DCs was developed to study TREM-1 blockade, and treatment with a TREM-1 blocking chimera decreased allogeneic Th17 activation, as well as IL-17 production. Furthermore, TREM-1 blockade of ex vivo psoriatic dendritic cells in an alloMLR also showed a decrease in IL-17. Together, these data suggest that the TREM-1 signaling pathway offers a novel therapeutic target to prevent the effects of inflammatory myeloid DCs in psoriasis. Monocytes were isolated by plastic adherence, treated with TLR agonists overnight, washed twice and harvested in RTL-buffer. RNA was extracted and processed for microarray. 3 groups and 3 replicates with a paired structure across replicates

A proteomic landscape of the spatiotemporal influence of Interleukin-33 (IL-33) in monocytes

Project description:Interleukin-33 (IL-33), a member of the IL-1 superfamily cytokines, is an endogenous danger signal and a nuclear-associated cytokine. It is one of the essential mediators of both innate and adaptive immune responses. Aberrant IL-33 signaling has been demonstrated to play a defensive role against various infectious and inflammatory diseases. Although the signaling responses mediated by IL-33 have been previously reported, the temporal signalingdynamicsare yet to be explored. Towards this end,we applied quantitative temporal phosphoproteomics analysis to elucidate pathways and proteins induced by IL-33 in THP1 monocytes. Employing TMT labeling-based quantitation and titanium dioxide (TiO2)-based phosphopeptide enrichment strategy followed by mass spectrometry analysis, we identified 14,515 phosphorylation sites mapping to 4,174 proteins across (0 min to 240 mins)time points.

Interleukin-26 potentiates type 2 skin inflammation in presence of interleukin-1β

Project description:Atopic dermatitis (AD) is a debilitating inflammatory skin disorder. Biologics targeting the IL-4/IL-13 axis are effective in AD, but there is still a large proportion of patients that do not respond to IL-4R blockade. Further exploration of potentially pathogenic T cell-derived cytokines in AD may lead to new effective treatments. This study aimed to investigate the downstream effects of IL-26 on skin in the context of type 2 skin inflammation. We found that IL-26 alone exhibited limited inflammatory activity in skin. However, in presence of IL-1β, IL-26 potentiated the secretion of TSLP, CXCL1 and CCL20 from human epidermis through JAK/STAT signaling. Moreover, in an in vivo AD-like skin inflammation model, IL-26 exacerbated skin pathology and locally increased type 2 cytokines, most notably of Il13 in skin T helper cells. Neutralization of IL-1β abrogated IL-26-mediated effects, indicating that the presence of IL-1β is required for full IL-26 downstream action in vivo. These findings suggest that the presence of IL-1β enables IL-26 to be a key amplifier of inflammation in the skin. As such, IL-26 may contribute to the development and pathogenesis of inflammatory skin disorders such as AD.

Protein phosphorylations, mediated by pro-inflammatory cytokines IL-32g and IL-17A/F

Project description:Global kinase activity induced by cytokines IL-32g and IL-17A/F were determined using peptide arrays representing phophorylation targets The objective of this study was to identify common and unique phosphorylation targets of pro-inflammatory cytokines IL-32 and IL-17. These cytokines are associated with the pathogenesis and severity of chronic inflammatory disorders, therefore signaling intermediates of these cytokines could be beneficial as alternate theraputic targets that may likely influence different inflammatory pathways.

Transcription profiling of skin from patients with moderate to severe atopic dermatitis before and after treatment with IL-4R? inhibitor dupilumab (REGN668/SAR231893)

Project description:Atopic dermatitis (AD) is the most common inflammatory skin disease, with high unmet need for new therapies that are safe for chronic use. Emerging data suggest that TH2-cytokines play important roles in a variety of allergic and atopic conditions, including asthma and AD. In early phase clinical trials, dupilumab (a fully human monoclonal antibody against IL-4R? that potently blocks IL-4 and IL-13 signaling) rapidly and markedly improved clinical measures in adults with either asthma (with elevated eosinophil counts) or moderate-to-severe AD. The pathomechanisms that may be impacted by IL-4/13 blockade in these disease settings have not yet been characterized in detail. Transcriptome analyses in pre- and post-treatment skin biopsies from patients with moderate-to-severe AD treated with dupilumab or placebo in two completed clinical trials 18 Patients with AD treated with dupilumab or placebo. 28 biopsies in lesional (LS) Skin (16 pre-treatment and 12 post-treatment). 12 biopsies in non-lesional (NL) Skin (7 pre-treatment and 5 post treatment)
