Importance: Glioblastoma is an incurable tumor, and the therapeutic options for patients are limited.
Objective: To determine whether the systemic administration of HER2-specific chimeric antigen receptor (CAR)-modified virus-specific T cells (VSTs) is safe and whether these cells have antiglioblastoma activity.
Design, Setting, And Participants: In this open-label phase 1 dose-escalation study conducted at Baylor College of Medicine, Houston Methodist Hospital, and Texas Children's Hospital, patients with progressive HER2-positive glioblastoma were enrolled between July 25, 2011, and April 21, 2014.
Introduction: This article presents our experiences in the field of forensic post-traumatic stress disorder (PTSD).
Objective: The study examined parameters of 30 patients with PTSD who were the subject of forensic expertise (PTSDF) and in 30 patients with PTSD who were not (PTSDN).
Methods: Clinical research and the battery of tests (Impact of Event Scale - IES, Mississippi Scale, and list of symptoms of PCL-M) covered a total of 60 male subjects with a verified diagnosis of PTSD.
Background: Thymic involution is a prominent characteristic of an aging immune system. When thymic function is reduced/absent, the peripheral T cell pool is subject to the laws of peripheral T cell homeostasis that favor survival/expansion of T cell receptors with relatively higher functional avidity for self-peptide/MHC complexes. Due to difficulties in assessing the TCR avidity in polyclonal population of T cells, it is currently not known whether high avidity T cells preferentially survive in aging individuals, and what impact this might have on the function of the immune system and development of autoimmune diseases.

The impact of T cell receptor (TCR) avidity on the development of lupus has not been investigated. We took advantage of a transgenic mouse strain (designated MTB) that has a diverse T cell population and a globally stronger reactivity to self.

We hypothesized that an incidence and/or kinetics of RBC-specific antibody formation in SCD patients is influenced by a linked inheritance of the hemoglobin beta S (HbbetaS) allele and a polymorphism rs660C/T in the neighboring Ro52 gene. We found that 75% of C/T heterozygous and only 30.

Reduced TCR sensitivity of mature T cells is thought to help control the autoreactivity in peripheral T cells. The molecular basis for reduced sensitivity of peripheral T cells is not known.

To determine the manner of setting the threshold for deletion, we created a unique transgenic mouse strain with a diverse T cell population and globally increased TCR avidity for self-peptide/MHC complexes. Despite the adaptations aimed at reducing T cell reactivity (reduced TCR levels and increased levels of TCR signaling inhibitor CD5), transgenic mice displayed more severe experimental allergic encephalomyelitis and lupus.

Recently we have shown that GILT is also expressed in mouse T cells, where it exerts an inhibitory role on T cell activation. In this study, we identified mitochondrial manganese superoxide dismutase (SOD2) as one of the key intermediaries affected by GILT expression in fibroblasts.

To provide an insight into the potential cross talk between T cells and smooth muscle cells (SMC) in atherogenesis, we investigated changes in gene expression caused by CD40 ligation in cultured vascular SMC and their consequences for monocyte activation. CD40 expression in human-cultured SMC was induced by 24-h treatment with tumor necrosis factor-alpha plus interferon-gamma followed by 12-h exposure to mouse myeloma cells stably expressing human CD154 or the corresponding control cells.
