In the past few years, exploring new therapeutic strategies to optimize treatment outcomes has occurred rapidly.

Virus-Specific T Cells: Promising Adoptive T Cell Therapy Against Infectious Diseases Following Hematopoietic Stem Cell Transplantation.

Hematopoietic stem cell transplantation (HSCT) is a life-saving therapy for various hematologic disorders. Due to the bone marrow suppression and its long recovery period, secondary infections, like cytomegalovirus (CMV), Epstein-Bar virus (EBV), and adenovirus (AdV), are the leading causes of morbidity and mortality in HSCT cases. Drug resistance to the antiviral pharmacotherapies makes researchers develop adoptive T cell therapies like virus-specific T cell therapy.

Novelty in improvement of CAR T cell-based immunotherapy with the aid of CRISPR system.

Introduction: Chimeric Antigen Receptor (CAR) T cells have tremendous potentials for cancer treatment; however, various challenges impede their universal use. These restrictions include the poor function of T cells in tumor microenvironments, the shortage of tumor-specific antigens and, finally, the high cost and time-consuming process, as well as the poor scalability of the method. Creative gene-editing tools have addressed each of these limitations and introduced next generation products for cell therapy.

Survival protection of patients undergoing hematopoietic stem cell transplantation: grounded theory.

Purpose: For patients with blood malignancies, hematopoietic stem cell transplantation (HSCT) is a significant challenge.

This study presents a deep understanding of the psychological process of the treatment including perception, emotion, interactions, and its consequences in patients undergoing HSCT.

Gut microbiota intervention by pre and probiotics can induce regulatory T cells and reduce the risk of severe acute GVHD following allogeneic hematopoietic stem cell transplantation.

Background: Acute graft-versus-host disease (aGVHD) is one of the leading causes of limitation and mortality after allogeneic hematopoietic stem cell transplantation (allo-HSCT). Numerous studies have shown that changes in the gut microbiome diversity increased post-transplant problems, including the occurrence of aGVHD. Probiotics and prebiotics can reconstitute the gut microbiota and thus increase bacterial metabolites such as short-chain fatty acids (SCFAs) that have immunomodulatory effects preventing aGVHD in recipients of allo-HSCTs.

MicroRNA-125b as a valuable predictive marker for outcome after autologous hematopoietic stem cell transplantation.

Background: Relapse is a frequent occurrence in autologous hematopoietic stem cell transplantation (AHSCT), and early relapse after AHSCT results in poor survival and low quality of life. Predictive marker determination for AHSCT outcomes could be helpful in the prevention of relapse through personalized medicine. Here the predictive value of circulatory microRNAs (miRs) expression for AHSCT outcomes was studied.

Besides, blood filtration strategies, such as hemoperfusion and plasmapheresis, are employed to lessen the load of inflammatory molecules.

NK cell therapy in relapsed refractory multiple myeloma.

Recent advances in adoptive cell therapy have considerably changed the paradigm of cancer immunotherapy. Although current immunotherapies could cure many patients with multiple myeloma (MM), relapsed/refractory MM (RR/MM) is still challenging in some cases. Natural killer (NK) cells are innate immune cells that exert effective cytotoxic activity against malignant cells like myeloma cells.

Cell-Based Therapy Approaches in Treatment of Non-obstructive Azoospermia.

The rate of infertility has globally increased in recent years for a variety of reasons. One of the main causes of infertility in men is azoospermia that is defined by the absence of sperm in the ejaculate and classified into two categories: obstructive azoospermia and non-obstructive azoospermia. In non-obstructive azoospermia, genital ducts are not obstructed, but the testicles do not produce sperm at all, due to various reasons.

Survival of Patients with Acute Myeloid Leukemia after Allogeneic Stem Cell Transplantation: An Experience in Developing Country.

Allogeneic stem cell transplantation (allo-SCT) is the highest potential treatment for long-term survival as post-remission therapy for acute myeloid leukemia (AML). The aim of this study was to estimate the overall survival (OS) of patients with AML after allo-SCT and to identify the factors affecting them as a prognostic factor for the survival of patients. In this retrospective cohort study, data of patients with AML who underwent allo-SCT at Taleghani bone marrow transplantation and cell therapy center in Tehran, Iran, from May 2009 to September 2016 were used.

Potential and challenges of placenta-derived decidua stromal cell therapy in inflammation-associated disorders.

Decidual stromal cells (DSCs) isolated from maternal part of placenta, like mesenchymal stromal cells (MSCs), are able to inhibit alloreactivity in-vitro but in a superior way which makes them an attractive alternative for anti-inflammatory therapies. In alloreactivity, when a strong immune response is developed against alloantigens, DSCs develop an anti-inflammatory environment, both through cell-to-cell contact and soluble factors, to prevent the adverse effects of alloantigens. In alloreactivity-associated inflammation, proinflammatory cytokines can be released and then involved in the up-regulation of inflammatory reactions which is one of the main causes of inflammatory related disorders.
