1. Culture of mouse peritoneal macrophages with mouse serum induces lipid bodies that associate with the parasitophorous vacuole and decrease their microbicidal capacity against Toxoplasma gondii
Lipid bodies [lipid droplets (LBs)] are lipid-rich organelles involved in lipid metabolism, signalling and inflammation. Recent findings suggest a role for LBs in host response to infection; however, the potential functions of this organelle in Toxoplasma gondii infection and how it alters macrophage microbicidal capacity during infection are not well unders

2. Deciphering the contribution of lipid droplets in leprosy: multifunctional organelles with roles in Mycobacterium leprae pathogenesis
Leprosy is an infectious disease caused by Mycobacterium leprae that affects the skin and nerves, presenting a singular clinical picture. Across the leprosy spectrum, lepromatous leprosy (LL) exhibits a classical hallmark: the presence of a collection of M. leprae-infected foamy macrophages/Schwann cells characterised by their high lipid content. The signifi

3. Lipid and energy contents in the bodies of queens of Atta sexdens rubropilosa Forel (Hymenoptera, Formicidae): pre-and post-nuptial flight
O vôo nupcial permite que machos e fêmeas se encontrem e copulem. Para isso, tanto o macho quanto a fêmea precisam de energia para efetuar tal atividade. Antes de partir do ninho de origem, machos e fêmeas estão bem nutridos e prontos para o acasalamento. Mas pouco se conhece sobre o teor de lipídeos e conteúdo energético pré-vôo nupcial (fêmeas v

4. Desenvolvimento de estratégia para extrusão de lipídios por engenharia genética, subsequente à análise genética da via exocítica da microalga Neochloris oleoabundans / Development of genetic engineering atrategy of lipids extrusior following the genetic analysis of exocytic pathway from micralga Neochloris oleoabudans
Há no mundo um consenso sobre a necessidade de se encontrar fontes de carbono renováveis para a substituição do petróleo. O cultivo de microalgas tem sido considerado uma alternativa promissora para suprir essas cadeias carbônicas e biocombustíveis, visto que são microorganismos fotossintetizantes que podem acumular grandes quantidades de triacilglic

5. A quercetina protege o fígado na lesão hepática induzida por tiocetamida (TAA) e suas complicações
Drug-induced liver injury is an increasing health problem and a challenge for physicians, regulatory bodies and the pharmaceutical industry, not only because of its potential severity and elusive pathogenesis but also because it is often inaccurately diagnosed, commonly missed entirely and more often not reported. Drug metabolism studies, together with patho

6. Acúmulo de ricina em sementes de mamona e silenciamento do gene em plantas geneticamente modificadas
Castor bean (Ricinus communis L.) is an oilseed of great economic and social importance. The oil extracted from its seeds is used in biodiesel production and as raw material for chemicals, cosmetics and lubricants. Besides the oil extracted from the seeds, their production chain generates side-products, which can be used as organic fertilizer of good quality

7. Do Archaea and bacteria co-infection have a role in the pathogenesis of chronic chagasic cardiopathy?
Chronic cardiopathy (CC) in Chagas disease is a fibrotic myocarditis with C5b-9 complement deposition. Mycoplasma and Chlamydia may interfere with the complement response. Proteolytic enzymes and archaeal genes that have been described in Trypanosoma cruzi may increase its virulence. Here we tested the hypothesis that different ratios of Mycoplasma, Chlamydi

8. Morfoanatomia de frutos e sementes em Apocynaceae / Morphoanatomy of fruits and seeds in Apoctnaceae
This paper had as objective contribute for the knowledge of Apocynaceae by a morph-anatomic survey data from fruits and seeds from species of the family. On this study, 13 species present in Brazil and distributed in three of the five families currently described, were included. Flowers, fruits and seeds in many development levels were collected, fixed and s

9. Participation of galectin-1 in the evolution of experimental histoplasmosis / Participação da galectina-1 na evolução da histoplasmose experimental
Galectin-1 (Gal-1) belongs an endogenous lectins family that recognizes -galactoside and participates of various biological activities. This lectin can modulate the innate and adaptative immune responses. Although, Gal-1 participates of various pathophysiological processes, in literature we did not find reports related to the participation of Gal-1 in fungal

10. Estudo da modulação de corpúsculos lipídicos em células epiteliais. / Study of the modulation of lipid bodies in epithelial cells.
Corpúsculos lipídicos (CLs) são inclusões citoplasmáticas compostas principalmente por triglicerídeos e ésteres de colesterol, sendo também depósitos intracelulares de ácido araquidônico (AA) que pode ser metabolizado para a formação de eicosanóides. A PGE2 é o principal metabólito da via do AA produzido por células epiteliais. É um potente

11. Mecanismos de formação papel dos corpúsculos lipídicos nos eosinófilos na resposta inflamatória alergica / Mechanisms of fomatiom of the Paper of the Lipid Bodies in Eosinophils in the allergic inflammatory response
Lipid bodies are lipid-rich cytoplasmic inclusions, which are candidates to play a major role in the formation of eicosanoid mediators during inflammatory response. Lipid body formation/function in vivo at sites of allergic inflammation were never investigated. Here, we studied lipid body formation in vivo within eosinophils recruited to sites of allergic in

12. Mechanisms of leukocyte lipid body formation and function in inflammation
An area of increasingly interest for the understanding of cell signaling are the spatio-temporal aspects of the different enzymes involved in lipid mediator generation (eicosanoid-forming enzymes, phospholipases and their regulatory kinases and phosphatases) and pools of lipid precursors. The compartmentalization of signaling components within discrete and d
