Forget mosquito bites. Volunteers let researchers inject them with the dengue virus in the name of science - and an experimental vaccine protected them. Next up, scientists plan to use this same strategy against dengue's cousin, the Zika virus. It's called a human challenge, a little-known but increasing type of research where healthy people agree to be deliberately infected in the quest for new or improved vaccines against a variety of health threats, from flu to malaria. Wednesday's dengue study offered more evidence that what sounds bizarre not only can be done safely, it can offer important clues for how well a shot might work. "What we're trying to do is accelerate vaccine research," said senior author Dr. Anna Durbin of Johns Hopkins University's school of public health. It may be the best way "to know if you have a stinker before you try to test it in thousands or tens of thousands of people." The dengue candidate proved highly promising, researchers reported in the journal Science Translational Medicine. Dengue fever may have slipped from the headlines as the related Zika virus sweeps through Latin America, but every year mosquito-borne dengue causes devastating outbreaks throughout the tropics and subtropics. While most people survive dengue with few or even no symptoms, more than 2 million a year suffer serious illness and about 25,000 die. Creating a vaccine has been tough. It must work against four separate strains of dengue, and a shot that's only partially protective might backfire. That's because people who survive one type of dengue can suffer worse symptoms if they're later infected with another strain. Enter an experimental vaccine created at the National Institutes of Health, made from four live but weakened dengue strains. Initial studies had suggested the shots were safe and promising. But, "we really wanted to have an early clue that it was go to work," especially against the hard-to-prevent dengue serotype 2, said Dr. Stephen Whitehead of NIH's National Institute of Allergy and Infectious Diseases, who led the vaccine development. Researchers at Hopkins and the University of Vermont gave 41 healthy people who'd never been exposed to dengue either a single dose of the vaccine or a dummy shot. Six months later, those volunteers were challenged - injected with a weakened version of that dengue-2 strain. The results were striking: All 21 people who'd gotten the real vaccine were completely protected - while all 20 who'd gotten a placebo had dengue virus in their bloodstream and either a mild rash or a temporary drop in white blood cell count, researchers reported Wednesday. This kind of study mimics "the closest that it can be to what may happen in natural infection," said Dr. Nikos Vasilakis, a virologist at the University of Texas Medical Branch in Galveston, who wasn't involved in the new work but calls the NIH shot "one of the better vaccine candidates." Based in part on the findings, the Butantan Institute in Brazil last month began recruiting 17,000 people, ages 2 to 59, for the final testing needed to prove how well the NIH vaccine works against dengue in real-world conditions, when it is spread by mosquitoes. A competing vaccine, made by Sanofi Pasteur, recently was approved by Brazilian regulators for ages 9 to 45. What about Zika, the dengue relative that's been linked to babies born with unusually small heads? Already, researchers are planning similar challenge studies that could start even before there's a vaccine candidate, Durbin said. "We see a Zika challenge model as really beneficial for not only vaccine development but also to learn more about Zika itself," she explained. "We know very little about Zika right now," including how long it stays in blood and other parts of the body. Key to these challenge studies: Scientists must modify a virus strain in the laboratory so that it doesn't make volunteers openly ill but still is strong enough to spark a mild infection, what Whitehead called "that perfect in-between." Plus, that mimics what happens with both dengue and Zika, where most people who become infected never report symptoms. Before deliberately infecting someone, "you have to know that it's a completely controllable situation, that it's a mild and controlled infection," said Dr. Beth Kirkpatrick, who directs the University of Vermont Vaccine Testing Center that tested the dengue model.

The 1014 nucleotides long gene-encoding β-mannanase from Bacillus subtilis strain MA139 was cloned using PCR. To obtain high expression levels in Pichia pastoris, the β-mannanase gene was optimized according to the codon usage bias of P. pastoris and fused downstream of GAP promoter. The reconstituted plasmid pGAP-mann was transformed into P. pastoris X-33 strain to constitutively express β-mannanase. When cultured at 28∈°C for 3 days protein yields up to 2.7 mg/mL was obtained with the enzyme activity of up to 230 U/mL. In comparison, wild-type gene product yielded 1.9 mg/mL and 170 U/mL, respectively indicating that the protein yield and enzyme activity were significantly improved by codon modification. After purification, the enzyme properties were characterized. The optimal activity was at pH 6.0 and 50∈°C. In the pH range of 3.0 to 9.0, β-mannanase showed above 60% of its peak activity. Among the numerous ions tested copper significantly inhibited the enzyme activity. These results suggested that codon-optimized β-mannanase expressed in P. pastoris could potentially be used as an additive in the feed for monogastric animals. © 2009 Humana Press.

Matrix metalloproteinase (MMP)-2 and MMP-9, two important members of the matrix metalloproteinase family, have been shown critical contributions in intra-tumor angiogenesis and invasion of tumor progression, and they might also play important roles in the angiogenesis as well as the pannus formation of rheumatoid arthritis (RA). In the present study, we used the immunohistochemistry, the immunofluorescence staining and the con-focal scanning methods to characterize the immunolocalization of MMP-2 and MMP-9 in RA synovium tissues. Our results showed that both MMP-2 and MMP-9 immunostaining could be found in synoviocytes and vascular endothelial cells. Moreover, our con-focal scanning also showed that MMP-2 could be found in infiltrating CD14+ monocytes and CD68+ macrophages, and MMP-9 could be found in infiltrating CD68+ macrophages in RA synovium tissues, while weak or negative staining of these two MMPs could be found in infiltrating CD20+B cells and CD3+T cells in RA synovium. Thus, our finding suggests that both MMP-2 and MMP-9 expressed by synoviocytes as well as certain infiltrating immune cells role importantly in the angiogenesis in RA progression.

Angiogenesis, as well as pannus formation within the joint, plays an important role in the erosion of articular cartilage and bone in the pathological process of rheumatoid arthritis (RA). Tissue factor (TF), an essential initiator of the extrinsic pathway of blood coagulation, is also involved in the angiogenesis and the pannus formation of RA progression. In the present study, we used immunofluorescence and confocal scanning methods to characterize TF immunolocalization in RA synovium. We showed that positive staining of TF could be immunolocalized in synoviocytes, CD19+ B cells and CD68+ macrophages, whereas weak or negative staining of tissue factor could be found in CD34+ endothelial cells of neo-vessels, CD3+ T cells and CD14+ monocytes in RA synovium tissues. Our study demonstrates a detailed local expression of TF in the rheumatoid synovium, and supports the notion that TF, expressed not only by the synoviocytes themselves, but also the infiltrating CD19+ B cells and CD68+ macrophages, is involved in the pannus invasion in the progression of rheumatoid arthritis. © 2013 Elsevier GmbH.

Rheumatoid arthritis (RA) is a chronic and systematic autoimmune inflammatory disease. Recently, a novel T cell subset, follicular helper CD4 T cell (Tfh cells) was found in relation to the pathogenesis and progression of RA, and increased numbers of circulating Tfh cells were found in RA patients. However, there is little evidence regarding the localization of Tfh cells in synovium tissues from RA patients, owing to the lack of an available method to characterize their localization in tissue. The aim of our present study was to characterize the Tfh cells in rheumatoid synovium tissues from RA patients by using immunohistochemistry and triple-fluorescence immunostaining methods. Our results showed that specific staining of CD4, CXCR5 and ICOS could be found on infiltrating immune cells in rheumatoid synovium tissues. The use of triple-fluorescence immunostaining and confocal laser scanning showed immunolocalization of CD4+CXCR5+ICOS+T cells (Tfh cells) in the rheumatoid synovium tissues, whereas these signals were absent in osteoarthritis (OA) synovium and in normal synovium tissues. Thus the data from our present preliminary study support the notion that CD4+CXCR5+ICOS+Tfh cells could be found in rheumatoid synovium tissues from RA patients, indicating the possibility that this T cell subset in synovium tissues may have important roles in the pathogenesis and progression of RA. © 2013 Elsevier GmbH.
