Regulatory T cells (Tregs) suppress antitumor immune responses. Cycles of Dendritic cells (DC) vaccination combined with cytokine-induced killer (CIK) cells (DC/CIK) treatment were significantly related with good prognosis. Therefore, we investigated whether increased cycles of immunotherapy could decrease frequency of Tregs in patients with resected non-small cell lung cancer (NSCLC). Previous study from our laboratory has determined that the optimal cutoff point of the cycle count was 3cycles. We examined the levels of Tregs and the related cytokines by flow cytometric and cytokine analysis in these patients after more than (≥) 3cycles or less than (<) 3cycles of DC/CIK cell treatment...

BACKGROUND Streptococcus pneumoniae can cause life-threatening illness, with invasive pneumococcal diseases (IPD) like meningitis, sepsis, bacteremic pneumonia, and bacteremia being major causes of morbidity and mortality. Studies have shown that patients who have had a cochlear implant, particularly children, have an increased risk of bacterial (pneumococcal) meningitis. Vaccination in patients with cochlear implants is important and recommended universally. The World Health Organization recommends the use of pneumococcal conjugate vaccines in all countries and considers their use to be a priority in all national immunization programs...

Phytohemagglutinin (PHA) is commonly used to evaluate cell-mediated immunocompetence. In chickens, PHA is typically injected intra-dermally (i.d.) into the skin (e.g., wing web, wattle, or footpad), and the tissue swelling response is monitored, whereby the extent of tissue swelling positively relates to the individual's cell-mediated immune system capabilities. Although i.d. injected PHA was shown to stimulate mononuclear cell and basophil infiltration to the site of injection, reports on temporal, qualitative, and quantitative aspects of the local cutaneous PHA response are limited...

Prophylactic and/or therapeutic vaccines have an important potential to control Trypanosoma cruzi (T. cruzi)infection. The involvement of regulatory/suppressor immune cells after an immunization treatment and T. cruzi infection has never been addressed. Here we show that a new trans-sialidase-based immunogen (TSf) was able to confer protection, correlating not only with beneficial changes in effector immune parameters, but also influencing populations of cells related to immune control. Regarding the effector response, mice immunized with TSf showed a TS-specific antibody response, significant delayed-type hypersensitivity (DTH) reactivity and increased production of IFN-γ by CD8+ splenocytes...

We describe novel plasmid DNA that encodes the full-length Japanese encephalitis virus (JEV) genomic cDNA and launches live-attenuated JEV vaccine in vitro and in vivo. The synthetic cDNA based on the sequence of JEV SA14-14-2 live-attenuated virus was placed under transcriptional control of the cytomegalovirus major immediate-early promoter. The stability and yields of the plasmid in E. coli were optimized by inserting three synthetic introns that disrupted JEV cDNA in the structural and nonstructural genes...

Paracoccidioidomycosis (PCM) is an infectious disease endemic to South America, caused by the thermally dimorphic fungi Paracoccidioides. Currently, there is no effective human vaccine that can be used in prophylactic or therapeutic regimes. We tested the hypothesis that the immunogenicity of the immunodominant CD4+ T-cell epitope (P10) of Paracoccidioides brasiliensis gp43 antigen might be significantly enhanced by using a hepatitis B virus-derived particle (VLP) as an antigen carrier. This chimera was administered to mice as a (His)6-purified protein (rPbT) or a replication-deficient human type 5 adenoviral vector (rAdPbT) in an immunoprophylaxis assay...

Background Core needle biopsy plays a crucial role as diagnostic tool for BC. Both Ki67 and likely tumor-infiltrating lymphocytes (TILs) in the near future are determining the kind of systemic therapy. The role of TILs in BC is still an issue for clinical research, albeit preliminary results of neoadjuvant and adjuvant clinical studies already now highlight the crucial impact of TILs on therapy response and survival. Methods Evaluation of related publications (pubmed) and meeting abstracts (ASCO, SABCS). Results The monoclonal antibody Ki67 recognizing a nuclear antigene in proliferating cells is a positive marker of therapy response and superior survival...

Tuberculosis (TB) remains a main public health concern and 10.4 million new cases occurred in 2015 around the world. BCG is the only approved vaccine against TB, but has variable efficacy and new vaccines are needed. We developed two new mTB vaccine candidates based on the recombinant fusion proteins, rCMX and rECMXformulated with Advax4, a new combination adjuvant combining delta inulin, CpG oligonucleotide and murabutide. When BALB/c mice were immunized three times intramuscularly with these vaccine formulationsInjection of Advax4 alone increased the percentage of lymphatic endothelial cells and activated macrophages (F480/CD11b(+)) in the draining lymph nodes consistent with a chemotactic adjuvant effect...

An inactivated split-virion trivalent influenza vaccine (IIV3; Vaxigrip®, Sanofi Pasteur) has been available globally since 1968. Here, we describe the results of an open-label, post-licensure trial (EudraCT no. 2014-005078-12) to confirm the immunogenicity and safety of the Southern Hemisphere 2015 formulation of IIV3. Adults 18-60 years of age and > 60 years of age (60 per age group) received a single 0.5-ml intramuscular injection of IIV3. Between baseline and day 21 after vaccination, hemagglutination inhibition (HAI) titers for each strain in IIV3 increased, on average, by at least 11-fold for younger adults and at least 5-fold for older adults...

Botulism is a fatal intoxication caused by botulinum neurotoxins (BoNTs), which are mainly produced by Clostridium botulinum and characterized by flaccid paralysis. The BoNTs C and D are the main serotypes responsible for botulism in animals, including buffaloes. Botulism is one of the leading causes of death in adult ruminants in Brazil due to the high mortality rates, even though botulism in buffaloes is poorly reported and does not reflect the real economic impact of this disease in Brazilian herds. Vaccination is reported as the most important prophylactic measure for botulism control, although there are no specific vaccines commercially available for buffaloes in Brazil...

Introduction Our understanding of the involvement of the immune system in cancer control has increased over recent years. However, the development of cancer vaccines intended to reverse tumor-induced immune tolerance remains slow as most current vaccine candidates exhibit limited clinical efficacy. The skin is particularly rich with multiple subsets of dendritic cells (DCs) that are involved to varying degrees in the induction of robust immune responses. Transcutaneous administration of cancer vaccines may therefore harness the immune potential of these DCs, however, this approach is hampered by the impermeability of the stratum corneum...

High-risk human papillomavirus (hrHPV) has been identified as a key factor in the development of cervical cancer. Integration of viral DNA into the host genome has been postulated as an important etiological event during cervical carcinogenesis. High-risk HPV DNA integration frequently results in either the deletion or interruption of the large fragment of E1 and E2 region and the overexpression of oncogenes E6 and E7 in the viral genome, and the activation of oncogenes and the inactivation of tumor suppressors in host genome...

In recent years, there have been a number of reports on the successful use of immunostimulatory complexes with saponins and viral glycoproteins as veterinary vaccines and in clinical trials for human medicine. The saponins Algiox, Sapanox and Pangisan were isolated and purified by HPLC from Allochrusa gypsophiloides, Saponaria officinalis and Gypsophila paniculata plants in Kazakhstan and they proved to have low toxicity in experiments with mice, chickens and chicken embryos. Algiox, Sapanox and Pangisan can be used to create immunostimulatory complexes (ISCOMs) similar to saponin-Quil-A-containing ISCOMs both in structure and in immunostimulatory efficiency...
