AI Article Synopsis

  • Multiple attempts have been made to create T cells from pluripotent stem cells (PSCs), but these T cells often show low activity and poor immune function.
  • The researchers outline a two-step method using an inducible PSC line (iR9-PSCs) that includes creating induced hematopoietic progenitor cells (iHPCs) in the lab and then transplanting them to develop functional T cells in living organisms.
  • This process takes 21 days for iHPCs to prepare and an additional 4 to 6 weeks for the T cells to mature after transplantation, offering a straightforward and repeatable technique for generating functional T cells for research purposes.

Article Abstract

Numerous efforts have been attempted to regenerate T cells in culture dish from pluripotent stem cells (PSCs). However, in vitro generated T cells exhibited extremely low activity and compromised immunocompetency in vivo. Here, we describe a two-step protocol for regenerating functional T cells using an inducible -PSC (iR9-PSCs) line. The procedure mainly includes generation of induced hematopoietic progenitor cells (iHPCs) in vitro, transplantation, and development of functional induced T cells (iT) in vivo via transplantation. The entire induction process in vitro requires 21 days before iHPCs transplantation. The development of mature T cells in vivo takes 4 to 6 weeks post-transplantation. We provide a simple and reproducible approach for functional T cell regeneration from iR9-PSCs for research purpose.

Background: The common drugs used for the treatment of Newly Diagnosed Multiple Myeloma (NDMM) include bortezomib and lenalidomide, but the adverse effects of lenalidomide cannot be ignored, especially when it is used in the initial therapy.

Methods: This retrospective study evaluated the efficacy and safety of a modified DVD regimen (pegylated liposomal doxorubicin, bortezomib, and dexamethasone) followed by lenalidomide in the treatment of NDMM. A total of 40 NDMM patients were treated with a reduced dose of pegylated liposomal doxorubicin (20 mg/m) on day 1, subcutaneous bortezomib (1.

Pulmonary arterial hypertension (PAH) is a syndrome characterized by increased pulmonary vascular resistance and elevated pulmonary artery pressure, ultimately leading to right heart failure and even death. Increasing evidence implicates the fat mass and obesity-associated protein (FTO) in various metabolic and inflammatory pathways; however, its role in pulmonary endothelial function and PAH remains largely unexplored. In this study, we examined the effects of endothelial cell-specific FTO knockout on PAH development.

Red blood cells (RBCs) serve as natural transporters and can be modified to enhance the pharmacokinetics and pharmacodynamics of a protein cargo. Affinity targeting of Factor IX (FIX) to the RBC membrane is a promising approach to improve the (pro)enzyme's pharmacokinetics. For RBC targeting, purified human FIX was conjugated to the anti-mouse glycophorin A monoclonal antibody Ter119.

The recent development of modular universal chimeric antigen receptor (CAR) T-cell platforms that use bifunctional adaptor intermediates to redirect engineered T-cell effector function has greatly expanded the capabilities of adoptive T-cell therapy, enabling safer and more comprehensive cancer treatment. However, universal CAR receptor systems rely on unstable transient recognition of tag-coupled intermediates for T-cell activation, and the array of targeting intermediates has been limited to antibodies and small molecules. Addressing these shortcomings, we engineered universal CAR T-cell receptors that can be covalently modified with synthetic biomaterials by accelerated SpyCatcher003-SpyTag003 chemistry for cancer-cell targeting.

Background: Optic nerve schwannomas are an extremely rare pathology in neurosurgery. Their origin is rather debatable given the structure of the optic nerve, which does not typically have Schwann cells therein. However, a number of clinical cases of optic nerve tumors classified as schwannomas have been described in the literature.
