Immunomonitoring of MSC-Treated GvHD Patients Reveals Only Moderate Potential for Response Prediction but Indicates Treatment Safety.

Mesenchymal stromal cells (MSCs) are used as salvage therapy to treat steroid-refractory acute graft-versus-host disease (aGvHD). We studied the immunological response to MSC treatment in 16 aGvHD patients by assessing lymphocyte profiles and three proposed aGvHD serum markers during the MSC treatment. Surprisingly, there were no obvious differences in the lymphocyte profiles between the responders and non-responders.

Low interleukin-2 concentration favors generation of early memory T cells over effector phenotypes during chimeric antigen receptor T-cell expansion.

Background: Adoptive T-cell therapy offers new options for cancer treatment. Clinical results suggest that T-cell persistence, depending on T-cell memory, improves efficacy. The use of interleukin (IL)-2 for in vitro T-cell expansion is not straightforward because it drives effector T-cell differentiation but does not promote the formation of T-cell memory.

Differential isoform expression and selective muscle involvement in muscular dystrophies.

Despite the expression of the mutated gene in all muscles, selective muscles are involved in genetic muscular dystrophies. Different muscular dystrophies show characteristic patterns of fatty degenerative changes by muscle imaging, even to the extent that the patterns have been used for diagnostic purposes. However, the underlying molecular mechanisms explaining the selective involvement of muscles are not known.

Interaction with intestinal epithelial cells promotes an immunosuppressive phenotype in Lactobacillus casei.

Maintenance of the immunological tolerance and homeostasis in the gut is associated with the composition of the intestinal microbiota. We here report that cultivation of Lactobacillus casei ATCC 334 in the presence of human intestinal epithelial cells promotes functional changes in bacteria. In particular, the interaction enhanced the immunosuppressive phenotype of L.

Cytokine response of human mononuclear cells induced by intestinal Clostridium species.

Altered composition of intestinal microbiota has been associated with various immunological disorders such as inflammatory bowel disease. Although Clostridium species are major inhabitants of the intestinal tract, their interaction with the host immunological system is yet poorly characterized. In this study, cytokine responses of human monocytic cell line THP-1 and peripheral blood mononuclear cells (PBMC) to six type strains representing common intestinal clostridial species were determined.

Expression of multiple nebulin isoforms in human skeletal muscle and brain.

Introduction: Nebulin is a large actin-binding protein of the skeletal muscle sarcomere. Multiple isoforms of nebulin are produced from the 183-exon-containing nebulin gene (NEB). Mutations in NEB cause nemaline myopathy, distal myopathy, and core-rod myopathy.
