Syngnathidae (seahorses, seadragons and pipefish) suffer significant losses from non-tuberculous mycobacteria. However, they produce markedly different lesions in response to the disease compared to other teleost species, notably infrequent granuloma formation. This study evaluated 270 syngnathid fish, from which 92 were diagnosed with mycobacteriosis by histopathology, culture or both. Microscopic lesions variably consisted of random foci of coagulative necrosis in multiple organs, containing high numbers of free bacteria and large aggregates or sheets of macrophages with cytoplasm laden with acid-fast bacilli...

We have read with interest the article by Piaserico et al. concerning the use of tumour necrosis factor-alpha (TNF-alpha) blocking agent adalimumab in psoriatic patients with concomitant hepatitis B virus (HBV) or hepatitis C virus (HCV). The authors describe 17 psoriatic patients affected by chronic HBV infection and 20 affected by chronic HCV who were successfully treated with adalimumab with no evidence of HBV or HCV reactivation in a mean follow-up period of 27 and 40 months, respectively. We have previously described our successful experience of treatment with anti-TNF-alpha therapy in 17 psoriatic patients (11 with past HBV infection, 5 with chronic HCV infection and one affected by both HBV and HCV) without the use of lamivudine or adenofovir, and can now report on long-term follow-up data (mean follow-up period of 60 months)...

BACKGROUND: In the previous in vitro study, we found that simvastatin decreased the protein expression of CD36, the scavenger receptor, and calpain-1, the Ca2+-sensitive cysteine protease, in oxidized low-density lipoprotein (oxLDL)-treated macrophages. In this in vivo study, we investigated whether simvastatin downregulates the expression of CD36 and calpain-1 and inhibits the inflammation and atherosclerosis in apolipoprotein E knockout (ApoE KO) mice. METHODS: Twenty male 6-week-old ApoE KO mice were divided into 2 groups: the ApoE KO group and the ApoE KO + simvastatin (ApoE KO + Sim) group...

The targeted delivery of tumor necrosis factor-α (TNF-α) with antibodies specific to splice isoforms of fibronectin [e.g., F8-TNF, specific to the extra-domain A (EDA) domain of fibronectin] has already shown efficacy against experimental sarcomas but has not yet been investigated in orthotopic sarcomas. Here, we investigated F8-TNF in a syngeneic K7 M2-derived orthotopic model of osteosarcoma as a treatment against pulmonary metastases, the most frequent cause of osteosarcoma-related death. Immunofluorescence on human osteosarcoma tissue confirmed the presence of EDA in primary tumors (PTs) as well as metastases...

INTRODUCTION: There is increasing evidence for the involvement of chronic inflammation and oxidative stress in the pathogenesis of Alzheimer's disease (AD). Nuclear factor erythroid 2-related factor 2 (Nrf2) is an anti-inflammatory transcription factor that regulates the oxidative stress defense. Our previous experiments demonstrated that kavalactones protect neuronal cells against Amyloid β (Aβ)-induced oxidative stress in vitro by Nrf2 pathway activation. Here, we tested an in vivo kavalactone treatment in a mouse model of AD...

BACKGROUND: Fine definition of targeted CD8+ T-cell epitopes and their human leucocyte antigen (HLA) class I restriction informs iterative improvements of HIV-1 T-cell vaccine designs and may predict early vaccine success or failure. Here, lymphocytes from volunteers, who had received candidate HIVconsv vaccines expressing conserved sub-protein regions of HIV-1, were used to define the optimum-length target epitopes and their HLA restriction. In HIV-1-positive patients, CD8+ T-cell responses predominantly recognize immunodominant, but hypervariable and therefore less protective epitopes...

Anti-tumor therapies based on anti-inflammatory effects have been considered in cancer treatment. Survival, proliferation and, resultantly, invasion and metastasis of tumor cells are regulated by local inflammatory mediators. Primary inflammatory cytokines, such as tumor necrosis factor (TNF), are targets for anticancer therapy. Several anti‑inflammatory agents isolated from natural products are becoming important chemopreventive and therapeutic agents for cancer. The present study aimed to investigate the expression of TNF‑α, nuclear factor‑κΒ (NF‑κΒ) and p38α mitogen-activated protein kinase (p38α) genes, associated with proliferation and inflammation in the Caco‑2 cell line treated with ethanolic and hexanic extracts of Calyptranthes grandifolia O...

Prolonged low-grade inflammation or smoldering inflammation is a hallmark of cancer. Mast cells form a heterogeneous population of immune cells with differences in their ultra-structure, morphology, mediator content, and surface receptors. Mast cells are widely distributed throughout all tissues and are stromal components of the inflammatory microenvironment that modulates tumor initiation and development. Although canonically associated with allergic disorders, mast cells are a major source of pro-tumorigenic (e...
