Larsen,†,‡ John Gibson,†,‡ Kenneth F. Bradstock,*,† Georgina J. Clark,*,† and Derek N. J. Hart*,† CD83 is a member of the Ig gene superfamily, first identified in activated lymphocytes. Since then, CD83 has become an important marker for defining activated human dendritic cells (DC). Several potential CD83 mRNA isoforms have been described, including a soluble form detected in human serum, which may have an immunosuppressive function. To further understand the biology of CD83, we examined its expression in different human immune cell types before and after activation using a panel of mouse Downloaded from and human anti-human CD83 mAb. The mouse anti-human CD83 mAbs, HB15a and HB15e, and the human anti-human CD83 mAb, 3C12C, were selected to examine cytoplasmic and surface CD83 expression, based on their different binding charac- teristics. Glycosylation of CD83, the CD83 mRNA isoforms, and soluble CD83 released differed among blood DC, monocytes, and monocyte-derived DC, and other immune cell types. A small T cell population expressing surface CD83 was identified upon T cell stimulation and during allogeneic MLR. This subpopulation appeared specifically during viral Ag challenge. We did not observe human CD83 on unstimulated human natural regulatory T cells (Treg), in contrast to reports describing expression of CD83 on http://www.jimmunol.org/ mouse Treg. CD83 expression was increased on CD4+, CD8+ T, and Treg cells in association with clinical acute graft-versus-host disease in allogeneic hematopoietic cell transplant recipients. The differential expression and function of CD83 on human immune cells reveal potential new roles for this molecule as a target of therapeutic manipulation in transplantation, inflammation, and autoimmune diseases.

Graft-versus-host disease (GVHD) remains an important cause of morbidity and mortality after allogeneic hematopoietic cell transplantation (allo-HCT). For decades, GVHD prophylaxis has included calcineurin inhibitors, despite their incomplete efficacy and impairment of graft-versus-leukemia (GVL). Distinct from pharmacologic immune suppression, we have developed what we believe is a novel, human CD83-targeted chimeric antigen receptor (CAR) T cell for GVHD prevention. CD83 is expressed on allo-activated conventional CD4+ T cells (Tconvs) and proinflammatory dendritic cells (DCs), which are both implicated in GVHD pathogenesis. Human CD83 CAR T cells eradicate pathogenic CD83+ target cells, substantially increase the ratio of regulatory T cells (Tregs) to allo-activated Tconvs, and provide durable prevention of xenogeneic GVHD.

    Differential effects of PD-L1 versus PD-1 blockade on myeloid inflammation in human cancer Noffar Bar, … , Kavita M. Dhodapkar, Madhav Dhodapkar JCI Insight. 2020. https://doi.org/10.1172/jci.insight.129353. Clinical Medicine In-Press Preview Hematology Immunology Introduction: PD-1 and PD-L1 have been studied interchangeably in the clinic as checkpoints to reinvigorate T cells in diverse tumor types. Data for biologic effects of checkpoint blockade in human premalignancy are limited. Methods: We analyzed the immunologic effects of PD-L1 blockade in a clinical trial of atezolizumab in patients with asymptomatic multiple myeloma (AMM), a precursor to clinical malignancy. Genomic signatures of PD-L1 blockade in purified monocytes and T cells in vivo were also compared to those following PD-1 blockade in lung cancer patients. Effects of PD-L1 blockade on monocyte-derived dendritic cells were analyzed to better understand its effects on myeloid antigen- presenting cells. Results: In contrast to anti-PD-1 therapy, anti-PD-L1 therapy led to a distinct inflammatory signature in CD14+ monocytes and increase in myeloid-derived cytokines (e.g. IL-18) in vivo. Treatment of AMM patients with atezolizumab led to rapid activation and expansion of circulating myeloid cells which persisted in the bone marrow. Blockade of PD-L1 on purified monocyte-derived dendritic cells (DCs) led to rapid inflammasome activation and synergized with CD40L-driven DC maturation, leading to greater antigen-specific T cell expansion. Conclusions: These data show that PD-L1 blockade leads to distinct systemic […] Find the latest version: https://jci.me/129353/pdf Differential effects of PD-L1 versus PD-1 blockade on myeloid inflammation in human cancer Noffar Bar1*, Federica Costa2,3*, Rituparna Das2*, Alyssa Duffy2*, Mehmet Samur4, Samuel McCachren2, Scott N.

  • Insulin-Like Growth Factor I Promotes Maturation and Inhibits Apoptosis of Immature Cord Blood Monocyte–Derived Dendritic Cells Through MEK and PI 3-Kinase Pathways

We pre- DC maturation and apoptosis. On the contrary, neutralizing viously reported that IGF-I promoted cord blood (CB)-naïve TNF-␣ significantly increased the IGF-I–induced up-regulation T-cell maturation and now show that IGF-I promoted maturation of CD83 and CD40. We conclude that IGF-I has maturation and of CB monocyte–derived dendritic cells (DC) with up-regulation survival effects on CB DC. These effects are mediated through of CD83, CD86, CD40, and major histocompatibility complex both MEK and PI 3-kinase pathways but not through the IGF-I (MHC) class II molecules, and down-regulation of mannose induction of TNF-␣ production by the DC.

These effects were blocked by specific mitogen-activated protein Abbreviations kinase kinase (MEK) inhibitor (PD98059) and phosphoinositol AV, annexin V 3-kinase inhibitor (LY294002).
