Modulation of peroxisomal compartment by Epstein-Barr virus.

Viruses utilize clever strategies of interacting with various cellular factors, to remodel an organelle function, for the establishment of successful infection. In recent decades, numerous studies revealed the exploitation of the peroxisomal compartment by viruses. Epstein-Barr virus (EBV) is a ubiquitous virus linked with various cancers and neurological disorders.

Dysbiosis of Gut Microbiota from the Perspective of the Gut-Brain Axis: Role in the Provocation of Neurological Disorders.

The gut-brain axis is a bidirectional communication network connecting the gastrointestinal tract and central nervous system. The axis keeps track of gastrointestinal activities and integrates them to connect gut health to higher cognitive parts of the brain. Disruption in this connection may facilitate various neurological and gastrointestinal problems.

Outer Membrane Vesicles: An Emerging Vaccine Platform.

Vaccine adjuvants are substances that improve the immune capacity of a recombinant vaccine to a great extent and have been in use since the early 1900s; they are primarily short-lived and initiate antigen activity, mainly an inflammatory response. With the developing technologies and innovation, early options such as alum were modified, yet the inorganic nature of major vaccine adjuvants caused several side effects. Outer membrane vesicles, which respond to the stressed environment, are small nano-sized particles secreted by gram-negative bacteria.

Shifting of cell cycle arrest from the S-phase to G2/M phase and downregulation of EGFR expression by phytochemical combinations in HeLa cervical cancer cells.
