In allogeneic hematopoietic stem cell transplantation (allo-SCT), alloreactive donor T cells mediate the graft-versus-leukemia effect but also attack nonhematopoietic tissues, causing graft-versus-host disease (GVHD). Reducing alloreactive T-cell trafficking to GVHD target tissues while allowing their access to bone marrow (BM) and spleen, major sites of malignant hematopoiesis, is a rational strategy for reducing the GVHD risk when using alloreactive T cells as a therapeutic. Here, we show that effector T-cell (Teff) entry into BM and spleen in unmanipulated mice and in mice that received transplantation without alloreactive T cells is augmented by pertussis toxin (PTX)-sensitive chemokine receptor signaling.

Background: Systemic sclerosis (SSc) is an autoimmune disease characterized by vascular injury and inflammation, followed by excessive fibrosis of the skin and other internal organs, including the lungs. CX3CL1 (fractalkine), a chemokine expressed on endothelial cells, supports the migration of macrophages and T cells that express its specific receptor CX3CR1 into targeted tissues. We previously reported that anti-CX3CL1 monoclonal antibody (mAb) treatment significantly inhibited transforming growth factor (TGF)-β1-induced expression of type I collagen and fibronectin 1 in human dermal fibroblasts.

Memory T cells are a heterogeneous population of immune cells that provide adaptive immunity. Its full recovery seems essential for graft-versus-tumor reactions that provide an opportunity for biological cure in patients with acute leukemia. The use of mismatched or haploidentical donors has increased, which has become possible because of modifications in graft versus host disease (GVHD) prophylaxis.

Background: Acute graft-versus-host disease (GVHD) is a major complication of allogeneic hematopoietic stem cell transplantation (allo-HSCT) with significant morbidity and mortality, and efficacy of currently available therapeutics are limited. Acute and chronic GVHD are similar in that both are initiated by antigen presenting cells and activation of alloreactive B-cells and T-cells, subsequently leading to inflammation, tissue damage, and organ failure. One difference is that acute GVHD is mostly attributed to T-cell activation and cytokine release, whereas B-cells are the key players in chronic GVHD.
