Universal CAR T-cell therapies are poised to revolutionize cancer treatment and improve patient outcomes. However, realizing these advantages in an allogeneic setting requires universal T-cells that can kill target tumor cells, avoid depletion by the host immune system, proliferate without attacking tissues. Here, we describe development of a novel immune-evasive scaffold using precise TALEN-mediated gene editing DNA matrices vectorized recombinant adeno-associated virus 6. We simultaneously...

Patients with nonalcoholic steatohepatitis (NASH) have increased expression of liver monocyte chemoattractant protein-1 (MCP-1), but its cellular source and contribution to various aspects NASH pathophysiology remain debated. We demonstrated CCL2 (which encodes MCP-1) in patients NASH, commensurately, a 100-fold increase hepatocyte Ccl2 mouse model accompanied by monocyte-derived macrophage (MoMF) infiltrate fibrosis. To test repercussions hepatocyte-derived MCP-1, we generated...

Adoptive cell therapy using chimeric antigen receptor (CAR) T cells has proven to be lifesaving for many cancer patients. However, its therapeutic efficacy been limited in solid tumors. One key factor this is cancer-associated fibroblasts (CAFs) that modulate the tumor microenvironment (TME) inhibit infiltration and induce "T dysfunction." Additionally, sparsity of tumor-specific antigens (TSA) expression CAR-directed tumor-associated (TAA) on normal tissues often results "on-target...

Dendritic cells (DC) express a functional NADPH oxidase and produce reactive oxygen species (ROS) upon interaction with microbes T cells. Exposure to ROS leads DC activation maturation, as evidenced by phenotypic changes. We have evaluated how endogenous production affects the cytokine secretion pattern cell-activating capacity of bone marrow-derived murine DC. treated scavengers, well from mice that lack (and thereby inherently deficient in production) produced significantly increased...

Thiazolidinediones (TZDs) are PPARγ agonists with potent insulin-sensitizing effects. However, their use has been curtailed by substantial adverse effects on weight, bone, heart, and hemodynamic balance. TZDs induce the deacetylation of K268 K293 to cause browning white adipocytes. Here, we show that targeted mutations resulting in constitutive (K268R/K293R, 2KR) increased energy expenditure protected from visceral adiposity diet-induced obesity augmenting brown remodeling adipose tissues....

CD38, a type II transmembrane glycoprotein expressed in many cells of the immune system, is involved cell signaling, migration and differentiation. Studies CD38 deficient mice (CD38 KO mice) indicate that this molecule controls inflammatory responses, although its involvement these responses depends on disease model analyzed. Here, we explored role control autoimmune using chicken collagen (col II) immunized C57BL/6-CD38 as collagen-induced arthritis (CIA). We demonstrate develop an...

CD5 is a lymphoid-specific transmembrane glycoprotein constitutively expressed on thymocytes and mature T B1a lymphocytes. Current data support the view that negative regulator of antigen-specific receptor-mediated signaling in these cells, this would likely be achieved through interaction with ligand/s (CD5L) still undefined nature immune or accessory cells. To determine functional consequence loss CD5/CD5L vivo, new transgenic mouse line was generated (shCD5EμTg), expressing circulating...

Objective Transforming growth factor β (TGFβ) plays a prominent role in the establishment of immunologic tolerance, and mice lacking TGFβ1 die multiorgan inflammation early life. TGFβ controls differentiation CD4+ lymphocytes into Treg cells or proinflammatory Th17 cells. Although this dual capacity is modulated by presence additional cytokines around activated cells, also dissociates Th17/Treg cell dose‐dependent manner mechanisms still unknown. The purpose study was to explore contribution...

Abstract Despite the remarkable success of autologous chimeric antigen receptor (CAR) T cells, some patients relapse due to tumor escape and low or uneven expression, among other mechanisms. Therapeutic options after are limited, emphasizing need optimize current approaches. In addition, there is a develop allogeneic “off-the-shelf” therapies from healthy donors that readily available at time treatment decision can overcome limitations To address both challenges simultaneously, we generated...

Antigen-specific immunotherapy of type 1 diabetes, typically via delivery a single native β cell antigen, has had little clinical benefit to date. With increasing evidence that diabetogenic T cells react against multiple antigens, including previously unappreciated neo-antigens can be emulated by mimotopes, shift from protein- epitope-based therapy is warranted. To this end, we aimed achieve efficient co-presentation major epitopes targeting both CD4+ and CD8+ cells. We have compared versus...
