Treatment Pathways and Health Outcomes of German Patients with Chronic Graft-Versus-Host Disease After Allogeneic Hematopoietic Cell Transplantation: A Retrospective Health Claims Data Analysis.

Background: Although chronic graft-versus-host-disease (cGvHD) is an important long-term complication after allogenic hematopoietic cell transplantation (allo-HCT) and is associated with increased healthcare resource utilization, real-world evidence is scarce.

Objectives: The aim of the study was to evaluate survival of patients with cGvHD in Germany and to analyze hospitalization and treatment patterns.

Patients And Methods: Based on a German claims database with 4.

Human bone marrow contains a subset of quiescent early memory CD8(+) T cells characterized by high CD127 expression and efflux capacity.

Even today it is still not completely understood how CD8(+) T-cell memory is maintained long term. Since bone marrow (BM) is a niche for immunological memory, we sought to identify long-lasting early memory CD8(+) T cells in this compartment. To achieve this, we looked for CD8(+) T cells that are able to efflux Rhodamine 123, a typical property of stem cells.

Human memory T cells from the bone marrow are resting and maintain long-lasting systemic memory.

In the bone marrow, a population of memory T cells has been described that promotes efficient secondary immune responses and has been considered to be preactivated, owing to its expression of CD69 and CD25. Here we show that human bone marrow professional memory T cells are not activated but are resting in terms of proliferation, transcription, and mobility. They are in the G0 phase of the cell cycle, and their transcriptome is that of resting T cells.

CCN1: a novel inflammation-regulated biphasic immune cell migration modulator.

In this study, we performed a comprehensive analysis of the effect of CCN1 on the migration of human immune cells. The molecule CCN1, produced by fibroblasts and endothelial cells, is considered as an important matrix protein promoting tissue repair and immune cell adhesion by binding various integrins. We recently reported that CCN1 therapy is able to suppress acute inflammation in vivo.

Adiponectin is a negative regulator of antigen-activated T cells.

Adiponectin (APN), a cytokine constitutively produced in fat tissue, has been shown to exert anti-inflammatory effects in various disease models. While the influence of APN on monocytic cells has been extensively studied in vitro, little is known about its role in T cells. In this study, we show that while <10% of human peripheral blood T cells express adiponectin receptors (AdipoRs) on their surface, most T cells store AdipoRs in intracellular compartments.

The VEGF/Rho GTPase signalling pathway: a promising target for anti-angiogenic/anti-invasion therapy.

It has become increasingly apparent that current antiangiogenic therapy elicits modest effects in clinical settings. In addition, it remains challenging to treat cancer metastasis through antiangiogenic regimes. Rho GTPases are essential for vascular endothelial growth factor (VEGF)-mediated angiogenesis and are involved in tumour cell invasion.
