abstract：:The innate immune system plays a critical role in host defense against mucosal bacteria. Campylobacter jejuni is a major cause of human gastroenteritis that usually resolves spontaneously within several days, suggesting that innate mechanisms are important to control the infection. However, the specific means by which...

abstract：:Ebola virus (EBOV) is a member of the filoviridae family that causes severe hemorrhagic fever during sporadic outbreaks, and no approved treatments are currently available. The multifunctional EBOV VP35 protein facilitates immune evasion by antagonizing antiviral signaling pathways and is important for viral RNA synth...

abstract：:The Campylobacter jejuni N-linked protein glycosylation pathway produces a heptasaccharide that is added to >65 periplasmic and membrane proteins and is also released into the periplasm as the free oligosaccharide (fOS). The fOS is a novel soluble component of the C. jejuni periplasmic space that exists in 10-fold gre...

abstract：:Bacterial pathogens release a number of toxins that are able to form pores in target host cells, which can result in their destruction. Due to this property of this subgroup of toxins, they are considered virulence factors. A lesser known ability of these toxins when present at lower concentrations that are insufficie...

abstract：:Human herpesviruses have latency and lytic replication phases in their lifecycle. Proper regulation of herpesviral lifecycle is essential for the evasion of host immune surveillance and development of their related diseases. Recent advancements indicate a role of a novel class of viral non-coding RNAs, microRNA (miRNA...

abstract：:Chloroquine (CQ) was the best and most heavily used drug in the fight against malaria. However, the effectiveness of CQ has declined with the emergence and spread of CQ-resistant (CQR) Plasmodium falciparum parasites. The primary determinant of CQ resistance in P. falciparum is mutations in the parasite's 'chloroquine...
