Phagocytic uptake of Encephalitozoon cuniculi by nonprofessional phagocytes.
Encephalitozoon cuniculi is an obligate intracellular, spore-forming parasite belonging to the microsporidia that can cause disseminated infection in immunocompromised persons. E. cuniculi spores infect host cells by germination, i.e., by explosively everting the polar filament, through which the spore contents (sporoplasms) are subsequently injected into the cytoplasm. In addition, we observed...
متن کاملBrucella abortus transits through the autophagic pathway and replicates in the endoplasmic reticulum of nonprofessional phagocytes.
Brucella abortus is an intracellular pathogen that replicates within a membrane-bounded compartment. In this study, we have examined the intracellular pathway of the virulent B. abortus strain 2308 (S2308) and the attenuated strain 19 (S19) in HeLa cells. At 10 min after inoculation, both bacterial strains are transiently detected in phagosomes characterized by the presence of early endosomal m...
متن کاملExploitation of the endocytic pathway by Orientia tsutsugamushi in nonprofessional phagocytes.
Orientia tsutsugamushi, a causative agent of scrub typhus, is an obligate intracellular bacterium that requires the exploitation of the endocytic pathway in the host cell. We observed the localization of O. tsutsugamushi with clathrin or adaptor protein 2 within 30 min after the infection of nonprofessional phagocytes. We have further confirmed that the infectivity of O. tsutsugamushi is signif...
متن کاملInservice Training of Nonprofessional Counselors
The training of counselors who work in a correctional institution setting presents a unique set of challenges. and yet no mention of it exists in the forensic psychiatry literature. There has been some writing about psychintric intervention with prisoners (e.g .. Roth and Ervin. 197P). but for the most part. on-the-line counseling work in correctional institutions is performed by people with li...
متن کاملNonprofessional Phagocytosis Can Facilitate Herpesvirus Entry into Ocular Cells
Phagocytosis is a major mechanism by which the mediators of innate immunity thwart microbial infections. Here we demonstrate that human herpesviruses may have evolved a common mechanism to exploit a phagocytosis-like entrapment to gain entry into ocular cells. While herpes simplex virus-1 (HSV-1) causes corneal keratitis, cytomegalovirus (CMV) is associated with retinitis in immunocompromised i...
