Neisseria meningitidis: pathogenesis and immunity.
The recent advances in cellular microbiology, genomics, and immunology has opened new horizons in the understanding of meningococcal pathogenesis and in the definition of new prophylactic intervention. It is now clear that Neissera meningitidis has evolved a number of surface structures to mediate interaction with host cells and a number of mechanisms to subvert the immune system and escape com...
متن کاملEvidence for naturally acquired T cell-mediated mucosal immunity to Neisseria meningitidis.
Naturally acquired protective immunity against Neisseria meningitidis is thought to partially explain the disparity between the high levels of carriage in the human nasopharynx and the rare incidence of disease. To investigate this immunity to Neisseria meningitidis at the mucosal level, in vitro cellular responses to outer membrane vesicle preparations derived from this pathogen were examined ...
متن کاملIn Vivo Adaptation and Persistence of Neisseria meningitidis within the Nasopharyngeal Mucosa
Neisseria meningitidis (Nme) asymptomatically colonizes the human nasopharynx, yet can initiate rapidly-progressing sepsis and meningitis in rare instances. Understanding the meningococcal lifestyle within the nasopharyngeal mucosa, a phase of infection that is prerequisite for disease, has been hampered by the lack of animal models. Herein, we compare mice expressing the four different human c...
متن کاملVaccine-induced opsonophagocytic immunity to Neisseria meningitidis group B.
The role of opsonophagocytosis (OP) in protection against meningococcal disease is controversial because patients with deficiencies in terminal complement proteins whose sera support OP but not bactericidal activity (BA) are at greatly increased risk of disease. We assayed complement-mediated BA and OP bactericidal activity in sera from 32 adults immunized with an outer membrane vesicle vaccine...
متن کاملThe Enigma of Human T-Cell Leukemia Virus Type-1 (HTLV-1) Infection in Iran
Human T-cell lymphotropic virus type-I (HTLV-I) was the first human retrovirus associated with malignancy. The prevalence of HTLV-I infection varies significantly in different regions of the world. In this study, the prevalence of HTLV-I infection among ethnic Jews living in Shiraz, South of Iran, was investigated. 286 blood samples were obtained. HTLV-1 antibody assay on serum samples was d...
