An allogeneic hematopoietic stem cell transplantation that triggers graft-vs.-host-disease (GVHD) involves T cells that do not come from the patient's bloodstream, but rather from the local progenitor cells of the donor tissue. A study from the University of Pittsburgh confirmed this finding after cloning and following these cells, revealing their origin and peculiarities.
“I have had this idea for a pretty long time. In the tissues there are antigen-presenting cells and there are T cells. And I felt like there is no reason why they are needed to be input from blood that it could be a largely local response. Then, the question was whether there would be a subset of cells in the tissues that could continue to sustain it,” lead author Warren Shlomchik told BioWorld.
The interleukin-2 receptor subunit γ (IL-2RG), also known as γc cytokine receptor or CD132, family of cytokines includes interleukin-2 (IL-2), IL-4, IL-7, IL-9, IL-15 and IL-21. These γc cytokines exert broad pleiotropic effects on the innate and adaptive immune system, and they all share the IL-2RG chain as part of its signaling receptor complex. Researchers from Regeneron Pharmaceuticals Inc. aimed to assess whether targeting γc cytokines may serve as a strategy for the prevention and treatment of T-cell-mediated disease.
Researchers from Neoleukin Therapeutics Inc. have described NEO-TRA1, a novel CD25-targeted de novo non-α agonist of the IL-2 receptor (IL-2R) designed to selectively expand Tregs.
Tonix Pharmaceuticals Holding Corp. has entered into a sponsored research agreement with Boston Children's Hospital to study TNX-1500, an Fc-modified anti-CD40L monoclonal antibody, for the prevention of graft-vs.-host disease (GVHD) after hematopoietic stem cell transplant (HSCT) in animals.
Word from Talaris Therapeutics Inc. of a patient death in its phase III study called Freedom-1 with allogeneic cell therapy FCR-001 renewed speculation about the company’s odds in living donor kidney transplant patients, where Medeor Therapeutics Inc. also is advancing a late-stage candidate.
Despite mostly positive data from the ongoing phase III study of Talaris Therapeutics Inc.’s lead asset, FCR-001, an allogeneic cell therapy for treating living donor kidney transplant patients, investors are stepping away. The Boston and Louisville, Ky.-based company’s stock took a hit June 20 as shares (NASDAQ:TALS) fell 36.7% to $4.51 each.
PERTH, Australia – Cynata Therapeutics Ltd. has regained rights to its Cymerus mesenchymal stem cell (MSC) product, CYP-001, for graft-vs.-host disease (GVHD) from former licensee Fujifilm Corp., with the two companies negotiating a new partnership under which Fujifilm will manufacture the product.

In a deal that could total about $602 million, Syndax Pharmaceuticals Inc. will collaborate with Incyte Corp. to develop and develop axatilimab, Syndax’s anti-CSF-1R monoclonal antibody. Syndax is to receive $117 million up front, a $35 million equity investment and could bring in another $350 million in regulatory, development and commercial milestone payments.
Sanofi SA has added to its general medicines portfolio with a $1.9 billion acquisition of Kadmon Holding Inc. and its recently-approved graft-vs.-host disease drug Rezurock (belumosudil).
