In summary, our present system virology is confirmed current hypothesis about HAM/TSP pathogenesis with more details. It seems that Immune-dysregulation especially different cytokines expression in ACs individuals has key role in develop to HAM/TSP. In the other hand, HTLV-1 is successive intracellular pathogens which advantage from human host for hosting, replication and expansion in the human...

Chlamydiae are obligate intracellular bacterial pathogens with an unusual biphasic lifecycle, which is underpinned by two bacterial forms of distinct structure and function. Bacterial entry and replication require a type III secretion system (T3SS), a widely conserved nanomachine responsible for the translocation of virulence effectors into host cells. Recent cell biology experiments supported ...

objective(s): the rotavirus nonstructural protein 4 (nsp4) is responsible for the increase in cytoplasmic calcium concentration through a phospholipase c-dependent and phospholipase c-independent pathways in infected cells. it is shown that increasing of intracellular calcium concentration in rotavirus infected cells is associated with the activation of some members of protein kinases family su...

silver nanoparticles are increasingly used in various fields of biotechnology and applications in the medicine. objectives of this study were optimization of production of silver nanoparticles using biotransformations by fusarium oxysporum, and a further study on the location of nanoparticles synthesis in this microorganism. the reaction mixture contained the following ingredients (final concen...

background and objectives: brucella, causative of brucellosis, has some potential virulence factors involved in brucella replication and its strategies to circumvent the immune response. one of them is the virb gene that encodes the type іv secretion system proteins (t4ss) involved in intracellular replication of organism. brucella virulence factor a ( bvf a), and urease ( ure ) has also been d...

The proton pump inhibitor omeprazole reduced the intracellular replication of Salmonella enterica serovar Typhimurium in RAW264.7 cells without affecting bacterial growth in vitro or the viability of the host cells. The mechanism was bacteriostatic and interfered with replication mediated by the virulence-associated SPI2 type III secretion system. The proton pump inhibitor bafilomycin A(1), in ...

introduction: anethole is the main constituent of pimpinella anisum l. (anise), a herbaceous annual plant which has several therapeutic effects. in the folk medicine, anise is employed as an antiepileptic drug. specifically, this study was focused on the cellular effect of anethole, an aromatic compound in essential oils from anise and camphor. anethole has various physiological effects on the ...

Brucella spp. are facultative intracellular pathogens that have the ability to survive and multiply in professional and non-professional phagocytes, and cause abortion in domestic animals and undulant fever in humans. The mechanism and factors of virulence are not fully understood. Nicotinamidase/pyrazinamidase mutant (pncA mutant) of Brucella abortus failed to replicate in HeLa cells, and show...
