CD1a and Factor XIIIa Immunohistochemistry in Leprosy: A Possible Role of Dendritic Cells in the Pathogenesis of Mycobacterium leprae Infection
(LIPPINCOTT WILLIAMS & WILKINS, 2009)
Leprosy is a curable chronic granulomatous infectious disease caused by the bacillus Mycobacterium leprae. This organism has a high affinity for skin and peripheral nerve cells. In the evolution of infections, the immune ...
Antimicrobial Activity of Diterpenes from Viguiera arenaria against Endodontic Bacteria
(MDPI AG, 2011)
Six pimarane-type diterpenes isolated from Viguiera arenaria Baker and two semi-synthetic derivatives were evaluated in vitro against a panel of representative microorganisms responsible for dental root canal infections. ...
Pimarane-type Diterpenes: Antimicrobial Activity against Oral Pathogens
(MOLECULAR DIVERSITY PRESERVATION INTERNATIONAL-MDPI, 2009)
Seven pimarane type-diterpenes re-isolated from Viguiera arenaria Baker and two semi-synthetic pimarane derivatives were evaluated in vitro against the following main microorganisms responsible for dental caries: Streptococcus ...
Lsa21, a novel leptospiral protein binding adhesive matrix molecules and present during human infection
(BIOMED CENTRAL LTDLONDON, 2008)
Background: It has been well documented over past decades that interaction of pathogens with the extracellular matrix (ECM) plays a primary role in host cell attachment and invasion. Adherence to host tissues is mediated ...
Transcriptional profiling reveals the expression of novel genes in response to various stimuli in the human dermatophyte Trichophyton rubrum
(BIOMED CENTRAL LTD, 2010)
Background: Cutaneous mycoses are common human infections among healthy and immunocompromised hosts, and the anthropophilic fungus Trichophyton rubrum is the most prevalent microorganism isolated from such clinical cases ...
The role of disulfide bridges in the 3-D structures of the antimicrobial peptides gomesin and protegrin-1: a molecular dynamics study
(FUNPEC-EDITORA, 2008)
Some antimicrobial peptides have a broad spectrum of action against many different kinds of microorganisms. Gomesin and protegrin-1 are examples of such antimicrobial peptides, and they were studied by molecular dynamics ...
Bioassay guided purification of the antimicrobial fraction of a Brazilian propolis from Bahia state
(BIOMED CENTRAL LTDLONDON, 2009-07-30)
Background: Brazilian propolis type 6 (Atlantic forest, Bahia) is distinct from the other types of propolis especially due to absence of flavonoids and presence of other non-polar, long chain compounds, but presenting good ...
Evidence of the presence of T helper type 17 cells in chronic lesions of human periodontal disease
(WILEY-BLACKWELL PUBLISHING, INC, 2009)
Periodontal disease is a chronic inflammation of the attachment structures of the teeth, triggered by potentially hazardous microorganisms and the consequent immune-inflammatory responses. In humans, the T helper type 17 ...
Expressed sequence tags (ESTs) from the salivary glands of the tick Amblyomma cajennense (Acari : Ixodidae)
(PERGAMON-ELSEVIER SCIENCE LTD, 2008)
The neotropical tick Amblyomma cajennense is a significant pest to domestic animals, the most frequently human-biting tick in South America and the main vector of Brazilian spotted fever (caused by Rickettsia rickettsii), ...
Doxycycline Dose-dependently Inhibits MMP-2-Mediated Vascular Changes in 2K1C Hypertension
(WILEY-BLACKWELL, 2011)
Hypertension induces vascular alterations that are associated with up-regulation of matrix metalloproteinases (MMPs). While these alterations may be blunted by doxycycline, a non-selective MMPs inhibitor, no previous study ...
