Vaccines against the HIV-1 virus offers the best hope for eliminating HIV-associated mortality. Recombinant adenovector type 5 (rAd5) vaccine is a potential candidate for preventive vaccine strategies. In this study, we evaluated the rAd5 prime/protein boost strategy in a murine model. We used rAd5 harboring single HIV-1 genes. These genes, including gag (p24) and exon1 of tat, were amplified from HIV-1 (clade A) RNA using nested PCR. Recombinant vectors were constructed, purified and then injected at 1012 viral particles into four groups, each comprising five mice...

OBJECTIVES: Interleukin-12 (IL-12) as a cytokine has been proved to have a critical role in stimulating the immune system and has been used as immunotherapeutic agents in cancer gene therapy. Chitosan as a polymer, with high ability of binding to nucleic acids is a good candidate for gene delivery since it is biodegradable, biocompatible and non-allergenic polysaccharide. The objective of the present study was to investigate the effects of cells transfected with IL-12 loaded chitosan nanoparticles on the regression of fibrosarcoma tumor cells (WEHI-164) in vivo...

OBJECTIVES: Based on a novel approach suggesting a role of adipose tissue in osteoarthritis (OA), we aimed to determine whether the infrapatellar fat pad (IFP) may affect joint cell functions through adipokines. METHODS: The conditioned media of IFP and subcutaneous adipose tissue from OA patients were used to determine the production of leptin and adiponectin, and to stimulate chondrocytes and fibroblast-like synoviocytes (FLS). Blocking experiments were carried out to evaluate the contribution of adipokines to IFP effects...

The aim of this study is to investigate the functional role of G protein-coupled receptor 30 (GPR30) in the epididymis. We found that GPR30 is expressed in the epithelium of the immature rat epididymis and is involved in chloride secretion into the caudal epididymis lumen. The short-circuit current (Isc) experiments showed that in primary cultured caudal epididymis epithelium, activation of GPR30 by its specific agonist G1 induced a mono-phasic current increase, and G15, the specific antagonist of GPR30, could completely inhibit the current induced by G1...

We investigated the effect of botulinum neurotoxin type A (BoNT-A) on mechanical allodynia and hyperalgesia associated with infraorbital nerve constriction (ION-CCI) in rats. ION-CCI rats received a subcutaneous BoNT-A injection into the whisker pad area on day 7 postoperatively and underwent pain assessment on days 14 and 21 postoperatively. Rats were assigned to one of four treatment groups (n=5 each): ION-CCI+BoNT-A 20pg (low-dose group), ION-CCI+BoNT-A 200pg (high-dose group), ION-CCI+saline, and Sham. Mechanical allodynia and hyperalgesia were evaluated preoperatively (baseline) and on days 7, 14, and 21 postoperatively...

Streptococcus pneumoniae (pneumococcus) is a human pathogen that can cause otitis media, pneumonia and, in severe cases, meningitis and bacteremia. The pneumococcus expresses PotD, a protein belonging to the polyamines transporter complex called PotABCD. PotD is a membrane-associated protein that binds polyamines and has been shown to be important for virulence. In this work we demonstrate that subcutaneous immunization with rPotD reduces the bacterial load in the nasal tissue of mice, following intranasal challenge with a type 6B pneumococcus...

Neuromuscular diseases of the gut alter the normal motility patterns. Although surgical intervention remains the standard treatment, preservation of the sphincter attached to the rest of the gut is challenging. The present study aimed to evaluate a bioengineered gut-sphincter complex following its subcutaneous implantation for 4 weeks in rats. Engineered innervated human smooth muscle sheets and innervated human sphincters with a predefined alignment were placed around tubular scaffolds to create a gut-sphincter complex...

AIMS: Experimental autoimmune encephalomyelitis (EAE) is considered a valid experimental model for multiple sclerosis, a chronic neuroinflammatory condition of the central nervous system. Additionally, some evidence has shown that some microbial products such as the bacterial lipopolysaccharide could lead to the activation of reactive immune cells, triggering neuroinflammation. Several studies have found that transcranial magnetic stimulation (TMS) may exert a neuroprotective effect. Therefore, we aimed to assess the effect of TMS on the neuroinflammation occurring in EAE...

BACKGROUND: Non-Hodgkin lymphomas (NHL) are the most frequent hemato-oncological malignancies. Despite recent major advances in treatment, a substantial proportion of patients relapses highlighting the need for new therapeutic modalities. Promissory results obtained in pre-clinical studies are usually not translated when moving into clinical trials. Pre-clinical studies are mainly conducted in animals with high tumor burden; instead patients undergo chemotherapy as first line of treatment and most likely are under remission when immunotherapies are applied...

Activation of α7 nAChRs has been shown to improve performance in a variety of nonclinical assays of cognitive function. The role of α7 nAChRs in cognitive processes is likely related to their role in modulating synaptic transmission and plasticity that have been reported in cell culture, brain slices, and intact animals. Here we report the effects of the α7 nAChR agonist FRM-17874 on synaptic plasticity within the hippocampal-medial prefrontal cortex pathway. Long-term potentiation (LTP) was generated by tetanic stimulation of CA1/subiculum region in urethane anesthetized male rats...

There is a high demand for public immunization against Rotavirus (RV), especially in Africa. In Africa, the attenuated RV vaccination is contraindicated in patients with immune diseases and nutrition deficiency. Therefore, the inactivated RV vaccine (IRVV) could be an alternative. In this study, we aimed to develop a pentavalent-IRVV using the most circulating RV strains in Egypt and evaluate it against the commercially available Rotarix(®) vaccine. Trial-IRVV was developed with 5% sucrose, 2% polysorbate-80, and adsorbed on Alum to potentiate the vaccine immune response...

REVIEW
Ruth J Davis, Christopher Silvin, Clint T Allen
Myeloid-derived suppressor cells (MDSCs) have garnered much attention in recent years as a potential target for altering the immunosuppressive tumor microenvironment in a variety of solid tumor types. The ability to accurately assess the immunosuppressive capacity of MDSCs is fundamental to the development of therapeutic approaches aimed at disabling these immunosuppressive functions. In this article we provide evidence that the use of CD3/28 coated microbeads leads to artefactual T-lymphocyte suppression due to sequestration of beads by MDSCs isolated from the spleens of wild-type mice bearing subcutaneous syngeneic, carcinogen-induced oral cavity carcinomas...
