Though many taste assessment methods exist, the assessment of zinc sulfate tast e acuity is a method that has been suggested to have diverse relationships to human health. A double-bli nded pilot study was conducted among 21 individuals to a nalyze the relationships between salivary CA6 concentrations, zinc sulfate taste acuity and self- reported frequency of illness. ELISA was performed to quantify CA6 concentrations, the Bryce-Smith and Simpson “Zinc Taste Test” (BS-ZTT) protocol and a Taste Intensity Visual Analog Scale (TI-VAS) were utilized to assess zinc sulfate taste acuity and a h ealth history questionnaire was used to determine the fre quency of illness. A statistically significant corr elation existed between CA6 concentration and zinc sulfate taste acuity determined via the BS-ZTT ( rs = 0.62; p = 0.03). A moderate statistically significant negativ e correlation was found between self-reported frequ ency of illness and BS-ZTT scores ( rs = -0.64, p = 0.034). Likewise, a strong statistically signifi cant negative correlation was found between self-reported frequen cy of illness and TI-VAS scores ( rs = -0.81, p = 0.003). The results of this pilot study suggest that zinc s ulfate taste acuity may be reflective of salivary C A6 concentration in addition to being a retrospective indicator of illness frequency.","PeriodicalId":88361,"journal":{"name":"American journal of immunology","volume":"127 11 1","pages":"107-113"},"PeriodicalIF":0.0,"publicationDate":"2014-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.3844/AJISP.2014.107.113","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70189759","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Several alterations in immunological and inflammatory processes are caused in response to tumor presence and both innate and adaptive immunity have effective mechanism to destroy tumor cells. Nevertheless, distinct tumor types developed mechanisms to evade anti-tumor immunological responses. Here, we revise researches regarding inflammation and immune response during cancer development, as well as cancer signaling pathways and immunotherapy that have been performed in Brazil.

Moringa oleifera Lam is a tree rich in proteins, vitamins, minerals and a variety of phytochemcals with health benefits. Among the reported health benefits are antioxidant and anti-inflammatory properties. The purpose of th is study was to investigate whether tea brewed from dried Moringa leaves would abrogate inflammation in a mouse model of acute lung inflammation induced by LPS or extracts prepared from dust collected from a swine confinement facility (DE). Mice were offered water or Moringa tea for seven days. Tea consumption was significantly greater than that of water consumptio n on days 1 and 6, but there were no significant di fferences in weight gain or food consumption. On day seven, mice from both groups were forced to inhale, via int ranasal challenge, either Phosphate Buffered Saline (PBS), Lipopolysaccharide (LPS) [10 μg mL -1 ] or DE [10%]. Compared to mice that drank water, mice that drank Moringa tea had significantly less protein (p<0.05) and cellular influx (p<0.0001) into the lung after inha lation of 10% DE. No difference in neutrophil migra tion into the lungs of water and M. tea groups after LPS or D E challenge was detected. But mice that drank tea h ad significantly (p<0.05) more neutrophils with apopto tic morphology after DE challenge. TNF-α expression 24 h after inhalation of 10% DE, was significantly highe r (p<0.05) in lungs of M. tea mouse group as compared to water group. This increase in TNF-α was accompanied by higher levels of pro and anti-i nflammatory cytokines. Finally, activation of c-Jun N-terminal Kinase (JNK) in lungs of M. tea+DE group 24 h post inhalation was decreased. Taken together these resu lts suggest that Moringa oleifera leaf tea exerts antiinflammatory properties on acute lung inflammation induced by swine confinement dust through a mechanism involving neutrophil regulation and JNK activation.","PeriodicalId":88361,"journal":{"name":"American journal of immunology","volume":"10 1","pages":"73-87"},"PeriodicalIF":0.0,"publicationDate":"2014-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.3844/AJISP.2014.73.87","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70190124","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objective of this study was to analyse two different polymorphisms, LTC4S-444 A/C and Cys-LTR1 927 T/C single nucleotide polymorphism and to determine whether there is an association between these polymorphisms and asthma development. The study included two groups (30 asthmatics and 30 healthy controls). They were genotyped for the LTC4S-444 A/C and CysLTR1 927 T/C polymorphisms by PCR-RFLP. Their total serum IgE levels and urinary LTE4 levels were measured by Enzyme Linked Immunosorbent Assay (ELISA). IgE levels and urinary leukotriene E4 levels were higher in patient group than control group. The genotype and allele frequencies of both LTC4S-444 A/C and CysLTR1 927 T/C polymorphism were not significantly different between asthmatic patients and control group. While urinary leukotriene E4 levels were significantly higher in variant types of LTC4 synthase (AC and CC) compared to wild type (AA).

It plays a major roles in the different stress responses that are triggered by low Oxygen (O2) levels and its expression is associated with cell survival. HIF-1 is a heterodimer protein that comprises the subunits HIF-1I± and HIF-1I². The HIF-1I± subunit is regulated by O2-dependent hydroxylation of proline and asparagine residues, which results in ubiquitination and subsequent proteasome degradation. It may also be regulated independently of O2. This review discusses the regulatory mechanisms and biological significance of HIF-1I± with regard to cancer development and immune regulation. HIF-1I± stabilization under hypoxic conditions is crucial to the survival of established tumors and cancer stem cells. HIF-1I± is included in the hallmarks of cancer that are related to energy metabolism, although there is clear evidence that this transcription factor might participate in other hallmarks, such as angiogenesis, invasion and metastasis, self-sufficiency in proliferation signals and even apoptosis evasion. With regard to immunology, HIF-1I± regulates Interleukin (IL)-1I², IL-8 and Heme-Oxygenase-1 (HO-1) and despite some conflicting results, HIF-1I± is considered to be an important component of innate immune cell-mediated inflammation. With regard to the adaptive immune response, HIF-1I± expression is related to Th17 polarization and Treg inhibition. Thus, the HIF-1I± signaling pathway has been designated as a promising target for new drugs in several studies.","PeriodicalId":88361,"journal":{"name":"American journal of immunology","volume":"10 1","pages":"215-224"},"PeriodicalIF":0.0,"publicationDate":"2014-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.3844/AJISP.2014.215.224","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70189779","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

All of the evidences presented here are based on published papers that used breast cancer cells with different phenotype characteristics in their research. We observed that oxidative stress could modulate by several manners the tumor progression and these effects are directly related to its concentration and time of cell exposure to these substances. Furthermore, oxidative stress produced and released by breast cancer cells is able to interfere in the metabolism of the adjacent normal cells in a manner that improve the survival of the neoplastic cells. In relation to breast cancer treatment, the role of oxidative stress is complex. At the same time that it can be responsible to the induction of cell death, oxidative stress can also modulate pathway that leads to increased expression of anti-apoptotic and resistance-related proteins. Therefore, the participation of oxidative stress in breast cancer is complex and very broad and its better understanding could be important to the development of more effective therapeutic strategies for the different forms clinically found of the disease.","PeriodicalId":88361,"journal":{"name":"American journal of immunology","volume":"10 1","pages":"207-214"},"PeriodicalIF":0.0,"publicationDate":"2014-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.3844/AJISP.2014.207.214","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70189769","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
