BACKGROUND: Acute lung injury (ALI) and acute respiratory distress syndrome (ARDS) are characterized by excess production of inflammatory factors. Alveolar type II (ATII) cells help repair damaged lung tissue, rapidly proliferating and differentiating into alveolar type I cells after epithelial cell injury. In ALI, the lack of viable ATII favors progression to more severe lung injury. ATII cells regulate the immune response by synthesizing surfactant and other anti-inflammatory proteins and lipids...

Chronic antibody-mediated rejection is the major cause of fading allograft function and loss after renal transplantation. Currently, pharmacological agents for the suppression of chronic antibody-mediated rejection are lacking. Non-selective proteasome inhibitors suppress antibody-mediated allograft rejection. However, extensive adverse side effects of these inhibitors severely limit their application. In contrast, immunoproteasome inhibition is effective in preclinical models of autoimmune diseases and was applied over weeks without obvious adverse side effects...

The objective of this study was to evaluate the use of immunosuppressive therapy with high-dose cyclosporine, high-dose azathioprine, and a combination of low-dose cyclosporine and azathioprine after tracheal reconstruction by using a trachea-mimetic graft of polycaprolactone (PCL) bellows-type scaffold in a rabbit model. Twenty-four healthy New Zealand white rabbits were used in the study. All underwent circumferential tracheal replacement using tissue-engineered tracheal graft, prepared from PCL bellows scaffold reinforced with silicone ring, collagen hydrogel, and human turbinate mesenchymal stromal cell (hTMSC) sheets...

Primary central nervous system (CNS) lymphomas represent a subgroup of malignancies with specific characteristics, an aggressive course, and unsatisfactory outcome in contrast with other lymphomas comparable for tumor burden and histological type. Despite the high sensitivity to conventional chemotherapy and radiotherapy, remissions are frequently short lasting. Treatment efficacy is limited by several factors, including the biology and microenvironment of this malignancy and the "protective" effect of the blood-brain barrier, which limits the access of most drugs to the CNS...

Modern methods for desensitization protocol rely heavily on combined apheresis therapy and Rituximab, a chimeric (murine and human) anti-CD20 antibody used in AB0 incompatible kidney transplants. Severe infusion related reactions due to the administration of Rituximab are reported in 10% of patients. These adverse reactions may hinder the completion of the desensitization protocol. Therefore, it's useful to test alternative B cell depleting therapies. Our clinical case focuses on a 41-year-old male who developed an adverse infusion reaction following the administration of Rituximab and was given Ofatumumab as an alternative treatment...

The PI3K/Akt/mTOR signalling network is activated in almost 90% of all glioblastoma, the most common primary brain tumour, which is almost invariably lethal within 15 months of diagnosis. Despite intensive research, modulation of this signalling cascade has so far yielded little therapeutic benefit, suggesting that the role of the PI3K network as a pro-survival factor in glioblastoma and therefore a potential target in combination therapy should be re-evaluated. Therefore, we used two distinct pharmacological inhibitors that block signalling at different points of the cascade, namely, GDC-0941 (Pictilisib), a direct inhibitor of the near apical PI3K, and Rapamycin which blocks the side arm of the network that is regulated by mTOR complex 1...

BACKGROUND/AIMS: Radiation therapy is an important treatment for thoracic cancer; however, side effects accompanied with radiotherapy lead to limited tumor control and a decline in patient quality of life. Among these side effects, radiation-induced lung injury (RILI) is the most serious and common. Hence, an effective remedy for RILI is needed. Mesenchymal stromal cells (MSCs) are multipotent adult stem cells that have been demonstrated to be an effective treatment in some disease caused by tissue damage...

BACKGROUND: Oral mucositis is a side effect of chemotherapy, head and neck radiotherapy, and targeted therapy, affecting over 75% of high-risk patients. Ulceration can lead to severe pain and difficulty with eating and drinking, which may necessitate opioid analgesics, hospitalisation and supplemental nutrition. These complications may disrupt cancer therapy, which may reduce survival. There is also a risk of death from sepsis if pathogens enter the ulcers of immunocompromised patients...

Acute allograft rejection remains common after liver transplantation despite modern immunosuppressive agents. In addition, the long-term side effects of these regimens, including opportunistic infections, are challenging. This study evaluated the safety and clinical feasibility of umbilical cord-derived mesenchymal stem cell (UC-MSC) therapy in liver transplant patients with acute graft rejection. Twenty-seven liver allograft recipients with acute rejection were randomly assigned into the UC-MSC infusion group or the control group...

CAR T-cells are autologous or allogeneic human lymphocytes that are genetically engineered to express a chimeric antigen receptor targeting an antigen expressed on tumor cells such as CD19. CAR T-cells represent a new class of medicinal products, and belong to the broad category of Advanced Therapy Medicinal Products (ATMPs), as defined by EC Regulation 2007-1394. Specifically, they are categorized as gene therapy medicinal products. Although CAR T-cells are cellular therapies, the organization for manufacturing and delivery is far different from the one used to deliver hematopoietic cell grafts, for different reasons including their classification as medicinal products...

Hepatitis C virus (HCV) is one of the leading causes of liver diseases and transplantation worldwide. The current available therapy for HCV infection is based on interferon-α, ribavirin and the new direct-acting antivirals (DAAs), such as NS3 protease and NS5B polymerase inhibitors. However, the high costs of drug design, severe side effects and HCV resistance presented by the existing treatments demonstrate the need for developing more efficient anti-HCV agents. This study aimed to evaluate the antiviral effects of sorbifolin (1) and pedalitin (2), two flavonoids from Pterogyne nitens on the HCV replication cycle...

Due to vigorous alloimmunity, an allograft is usually rejected without any conventional immunosuppressive treatment. However, continuous global immunosuppression may cause severe side effects, including tumors and infections. Mounting evidence has shown that cyclosporine (CsA), a common immunosuppressant used in clinic, impedes allograft tolerance by dampening regulatory T cells (Tregs), although it inhibits allograft rejection at the same time. Therefore, it is necessary to seek an alternative immunosuppressive drug that spares Tregs with high efficiency in suppression but low toxicity...

Allogeneic hematopoietic stem cell transplantation is the only curative treatment option for several hematological malignancies and immune deficiency syndromes. Nevertheless, the development of a graft-versus-host disease (GvHD) after transplantation is a high risk and a severe complication with high morbidity and mortality causing therapeutic challenges. Current pharmacological therapies of GvHD lead to generalized immunosuppression followed by severe adverse side effects including infections and relapse of leukemia...
