TNF-alpha activates human monocytes for Paracoccidioides brasiliensis killing by an H2O2-dependent mechanism
(Taylor & Francis Ltd, 2006-06-01)
Human monocytes activated by recombinant tumor necrosis factor alpha (TNF-alpha) exhibited significant fungicidal activity on the yeast cells of a highly virulent strain of Paracoccidioides brasiliensis. This process was ...
FUNGITOXICITY OF ESSENTIAL OILS ON Plasmopara viticola, CAUSAL AGENT OF GRAPEVINE DOWNY MILDEW
(Soc Brasileira Fruticultura, 2017-01-01)
This study aimed to evaluate the fungitoxic (antifungal) effect of seven essential oils on Plasmopara viticola, the causal agent of grapevine downy mildew. The cinnamon, eucalyptus globulus, marjoram, melaleuca, peppermint, ...
High expression of human monocyte iNOS mRNA induced by Paracoccidioides brasiliensis is not associated with increase in NO production
(Elsevier B.V., 2012-10-01)
In this study we investigated the role of nitric oxide (NO) in monocyte fungicidal activity against Paracoccidioides brasiliensis. We found that cells primed with IFN-gamma, TNF-alpha or GM-CSF and challenged with a ...
Study of bronchoalveolar lavage fluid in paracoccidioidomycosis: cytopathology and alveolar macrophage function in response to gamma interferon; comparison with blood monocytes
(Elsevier B.V., 2003-12-01)
Patients with paracoccidioidomycosis (PCM) present marked involvement of the lungs during the course of the mycosis. The purpose of this work was to obtain bronchoalveolar lavage (BAL) fluid from these patients to study ...
Immunomodulatory activities associated with β-glucan derived from Saccharomyces cerevisiae
In this study we investigated the effect of β-glucan derived from Saccharomyces cerevisiae on fungicidal activity, cytokine production and natural killer activity. Spleen and peritoneal cells from female C57BL/6 mice, ...
First study of hormesis effect on mushroom cultivation
The use of fungicides is common in mushroom cultivation, but no study was carried out applying reduced doses of fungicides in order to increase yield, taking account the hormesis effect. The aim of this manuscript was to ...
Interleukin-15 increases Paracoccidioides brasiliensis killing by human neutrophils
(Universidade Estadual Paulista (UNESP), Centro de Estudos de Venenos e Animais Peçonhentos (CEVAP), 2014)
Impact of foliar nickel application on urease activity, antioxidant metabolism and control of powdery mildew (Microsphaera diffusa) in soybean plants
Nickel (Ni) is a cofactor for urease, an enzyme that breaks down urea into ammonia and carbon dioxide. This study aimed to evaluate the physiological impact of Ni on urea, antioxidant metabolism and powdery mildew severity ...
