Avaliação do perfil de citocinas séricas e óxido nítrico na hanseníase experimental murina

Hansen. int; 49 (), 2024
Introdução: a hanseníase é uma do-ença infecciosa crônica causada pelo Mycobacterium leprae (M. leprae), um para-sita intracelular obrigatório. Assim, a resis-tência do hospedeiro a esse patógeno depen-de da imunidade celular. O uso de modelos experimentais tem permitido...

Trasplante pulmonar: una perspectiva desde la inmunología

Resumen El trasplante pulmonar implica una serie de desafíos, que como lo ha demostrado la historia, no sólo depende de un adecuado desarrollo de técnicas quirúrgicas, sino también de la comprensión de una serie de complejas interacciones inmunológicas celulares y humorales que serán las responsa...

Abstract Acute respiratory distress syndrome (ARDS) is a respiratory process of acute onset, showing on X rays as bilateral pulmonary infiltrates and severe respiratory failure, Coccidiodomycosis is a unusual cause of acute respiratory distress syndrome, the incidence of coccidiomycosis in a solid organ ...

Experimental studies using OMV in a new platform of SARS-CoV-2 vaccines

Although COVID-19 vaccines have recently been approved for emergency use, search for new vaccines are still urgent, since the access of the countries, especially the poorest, to the vaccines, has shown to be slower than the necessary to rapidly control the pandemic. We proposed a novel platform for vacci...

Las células dendríticas plasmacitoides evocan la respuesta efectora de los linfocitos T citotóxicos específicos para Salmonella

Biomédica (Bogotá); 39 (supl.2), 2019
Resumen Introducción. La función inmunológica de las células dendríticas plasmacitoides durante las infecciones bacterianas, como la de Salmonella spp., es poco conocida. En ese contexto, se analizó su función efectora para presentar antígenos de Salmonella Typhimurium ante linfocitos T citotóx...

Mecanismos efetores da resposta imune na infecção por Bordetella pertussis

A coqueluche é uma doença infecciosa aguda, transmissível, com predileção pelo trato respiratório, caracterizada por paroxismos de tosse seca e considerada uma importante causa de morbidade e mortalidade infantil. A resposta imunológica humoral e celular do hospedeiro promove a contenção da infe...

Subsets of T lymphocytes in the lesional skin of pityriasis rosea

An. bras. dermatol; 94 (1), 2019
Abstract: Background: Pityriasis rosea is a common papulosquamous disorder. However, its etiology and pathogenesis remain unclear. Objective: We investigate the types of inflammatory cells infiltrating the lesional skin of pityriasis rosea and demonstrate whether T-cell-mediated immunity is involved in...

Β-Glucan of candida albicans cell wall extract inhibits salmonella typhimurium colonization by potentiating cellular immunity (cd8 + and cd4 + t cells)

Abstract INTRODUCTION: Antimicrobial resistance has been reported in the drugs used for the treatment of typhoid fever. The immunomodulatory substance β-glucan can be used as an alternative therapy as it potentiates host immunity. The aims of this study are to observe the effect of Candida albicans...

Immune response and biochemistry of calves immunized with rMSP1a ( Anaplasma marginale) using carbon nanotubes as carrier molecules

Abstract Vaccination against Anaplasma marginale has been considered an important control strategy for bovine anaplasmosis. Recently, mice immunized with rMSP1 a linked to carbon nanotubes (MWNT) showed significant immune responses, generating a new possibility for use of an inactivated vaccine. The obj...
