Neuroaxonal pathology is a main determinant of disease progression in multiple sclerosis; however, its underlying pathophysiological mechanisms, including its link to inflammatory demyelination and temporal occurrence in the disease course are still unknown. We used ultra-high field (7 T), ultra-high gradient strength diffusion and T1/T2-weighted myelin-sensitive magnetic resonance imaging to characterize microstructural changes in myelin and neuroaxonal integrity in the cortex and white matter in early stage multiple sclerosis, their distribution in lesional and normal-appearing tissue, and their correlations with neurological disability...

Several retrospective studies in children with B cell precursor (BCP) acute lymphoblastic leukemia (ALL) provided clinical evidence that higher absolute lymphocyte counts (ALC) early into treatment significantly correlated with improved relapse-free and overall survival. It still remains unknown, however, whether the predictive role of higher ALCs reflects general bone marrow recovery or a more specific attribute of immune function. To investigate this question, we implemented a prospective observational cohort study in 20 children with BCP ALL on day 29 (D29) of induction chemotherapy and immunophenotyped their lymphoid (T, B and natural killer cells) and myeloid (neutrophils, monocytes, dendritic cells) compartments...

Renal cell carcinomas with t(6;11) chromosome translocation involving the TFEB gene are indolent neoplasms which often occur in young patients. In this study, we report seven cases of renal cell carcinoma with TFEB rearrangement, two of whom had histologically proven metastasis. Patients (4F, 3M) ranged in age from 19 to 55 years (mean 37). One patient developed paratracheal and pleural metastases 24 months after surgery and died of disease after 46 months; another one recurred with neoplastic nodules in the perinephric fat and pelvic soft tissue...

REVIEW
Matthew J Wieduwilt
Treatment of older patients with Philadelphia-chromosome-positive (Ph+) acute lymphoblastic leukemia presents unique challenges. Advanced age, comorbidities, high treatment-related death rates with traditional chemotherapy, and relapse combine to yield poor survival. Reduced-intensity induction with BCR-ABL1 targeted tyrosine kinase inhibitors (TKIs) and corticosteroids yields CR rates 96-100% with no induction mortality but relapse is nearly certain without effective consolidation. Few clinical trials provide guidance on optimal consolidation for older Ph+ ALL...

REVIEW
Kristen M O'Dwyer, Jane L Liesveld
Older adults with Philadelphia chromosome negative (Ph-),-B-cell acute lymphoblastic leukemia (ALL) have the highest rates of treatment failure and treatment complications with current therapy, and, thus, there is no standard treatment for these patients. Approximately 16 percent of patients with newly diagnosed Ph- B-cell ALL are aged 60 years or older [1]. The five-year overall survival for this older cohort of patients is approximately 20 percent, and there has been no improvement in their survival in decades [2]...

The clinical significance of regulatory T cells (Treg) and tumor-associated macrophages (TAM) in the tumor microenvironment of human bladder cancer remains unclear. The aim of this study is to explore their relevance to oncological features in non-muscle invasive bladder cancer (NMIBC). We carried out immunohistochemical analysis of forkhead box P3 (FOXP3, Treg maker), CD204 (TAM marker), and interleukin-6 (IL6) using surgical specimens obtained from 154 NMIBC patients. The Treg and TAM counts surrounding the cancer lesion and IL6-positive cancer cell counts were evaluated against clinicopathological variables...

High rates of telomerase reverse transcriptase (TERT) promoter mutations have recently been described in urothelial carcinoma (UC). Unlike UC in the bladder, adenocarcinomas account for the majority of urachal cancer (UrC) cases. As data in UrC is unclear, we analyzed TERT promoter mutations in a large cohort of UrC for its differential diagnostic, clinicopathological and prognostic significance. UrC cases from six academic centers were analyzed for c.-146C>T (C250T) and c.-124C>T (C228T) TERT promoter mutations by PCR and Sanger sequencing...

Biological aging is associated with immune activation (IA) and declining immunity due to systemic inflammation. It is widely accepted that HIV infection causes persistent IA and premature immune senescence despite effective antiretroviral therapy and virologic suppression; however, the effects of combined HIV infection and aging are not well defined. Here, we assessed the relationship between markers of IA and inflammation during biological aging in HIV-infected and -uninfected populations. Antibody response to seasonal influenza vaccination was implemented as a measure of immune competence and relationships between IA, inflammation, and antibody responses were explored using statistical modeling appropriate for integrating high-dimensional data sets...

Dysembryoplastic neuroepithelial tumor (DNT) has traditionally been viewed as rare benign tumors that present with seizure widely considered curable with surgery alone. Most DNTs occur in childhood and young adults. However, rare reported cases occur in infants. This paper reported an infant case of DNT and its diagnosis, differential diagnosis, treatment, molecular features and prognosis based on the review of current literatures. The age onset of this patient was only 11 months old. The clinical manifestations were partial seizures and the imaging data untypical; CT and MRI were all supportive of astrocytoma...

Distinct molecular pathways govern the differentiation of CD8(+) effector T cells into memory or exhausted T cells during acute and chronic viral infection, but these are not well studied in humans. Here, we employed an integrative systems immunology approach to identify transcriptional commonalities and differences between virus-specific CD8(+) T cells from patients with persistent and spontaneously resolving hepatitis C virus (HCV) infection during the acute phase. We observed dysregulation of metabolic processes during early persistent infection that was linked to changes in expression of genes related to nucleosomal regulation of transcription, T cell differentiation, and the inflammatory response and correlated with subject age, sex, and the presence of HCV-specific CD4(+) T cell populations...

REVIEW
Ira Tabas, Andrew H Lichtman
Atherosclerosis is an arterial disease process characterized by the focal subendothelial accumulation of apolipoprotein-B-containing lipoproteins, immune and vascular wall cells, and extracellular matrix. The lipoproteins acquire features of damage-associated molecular patterns and trigger first an innate immune response, dominated by monocyte-macrophages, and then an adaptive immune response. These inflammatory responses often become chronic and non-resolving and can lead to arterial damage and thrombosis-induced organ infarction...

Aims: The co-stimulatory receptor CD27 modulates responses of T cells, B cells, and NK cells. Various T cell subsets participate in atherogenesis. However, the role of CD27 in atherosclerosis remains unexplored. Methods and results: Here we investigated the effect of bone marrow-derived and systemic CD27 deficiency in Apolipoprotein E-deficient (Apoe-/-) mice in early and advanced stages of atherosclerosis. Lethally-irradiated Apoe-/- mice reconstituted with Cd27-/-Apoe-/- bone marrow and consuming an atherogenic diet displayed a markedly increased plaque size and lesional inflammation compared to mice receiving Cd27+/+Apoe-/- bone marrow...
