Correction of T-Cell Repertoire and Autoimmune Diabetes in NOD Mice by Non-myeloablative T-Cell Depleted Allogeneic HSCT.

The induction of partial tolerance toward pancreatic autoantigens in the treatment of type 1 diabetes mellitus (T1DM) can be attained by autologous hematopoietic stem cell transplantation (HSCT). However, most patients treated by autologous HSCT eventually relapse. Furthermore, allogeneic HSCT which could potentially provide a durable non-autoimmune T-cell receptor (TCR) repertoire is associated with a substantial risk for transplant-related mortality.

Case report: Robust response of metastatic clear cell sarcoma treated with cabozantinib and immunotherapy.

Clear Cell Sarcoma (CCS), also referred to as malignant melanoma of soft parts, is a rare and aggressive malignant tumor. It comprises 1% of all soft tissue sarcomas and is known to be radio- and chemotherapy resistant. CCS shares morphological and immunohistochemical features with malignant melanoma, including melanin biosynthesis and melanocytic markers.

Toward safer haploidnetical hematopoietic stem cell transplantation.

The use of haploidentical HSCT is gaining momentum using either megadose T-cell depleted (TCD) myeloablative HSCT, or T cell replete nonmyeloablative HSCT in conjunction with cyclophosphamide post-transplant (PTCY). However, the risks of myeloablative protocols in the former or prolonged immunosuppression in the later, adversely impacting GVL and anti-pathogen immunity are challenging. Recently, we demonstrated in a stringent BM allografting murine model, that combining megadose TCD HSCT with PTCY, enabled durable chimerism induction without GVHD in the absence of any immune suppression after CY.
