The 4EHP-mediated translational repression of cGAS impedes the host immune response against DNA viruses.

A critical host response against viral infections entails the activation of innate immune signaling that culminates in the production of antiviral proteins. DNA viruses are sensed by the cytosolic pattern recognition receptor cyclic GMP-AMP synthase (cGAS), which initiates a signaling pathway that results in production of proinflammatory cytokines such as Interferon-β (IFN-β) and activation of the antiviral response. Precise regulation of the antiviral innate immune response is required to avoid deleterious effects of its overactivation.

Interferon-γ couples CD8 T cell avidity and differentiation during infection.

Effective responses to intracellular pathogens are characterized by T cell clones with a broad affinity range for their cognate peptide and diverse functional phenotypes. How T cell clones are selected throughout the response to retain a breadth of avidities remains unclear. Here, we demonstrate that direct sensing of the cytokine IFN-γ by CD8 T cells coordinates avidity and differentiation during infection.

The Current Landscape of mRNA Vaccines Against Viruses and Cancer-A Mini Review.

Both infectious viral diseases and cancer have historically been some of the most common causes of death worldwide. The COVID-19 pandemic is a decidedly relevant example of the former. Despite progress having been made over past decades, new and improved techniques are still needed to address the limitations faced by current treatment standards, with mRNA-based therapy emerging as a promising solution.

Inhibitory interneurons mediate autism-associated behaviors via 4E-BP2.

Translational control plays a key role in regulation of neuronal activity and behavior. Deletion of the translational repressor 4E-BP2 in mice alters excitatory and inhibitory synaptic functions, engendering autistic-like behaviors. The contribution of 4E-BP2-dependent translational control in excitatory and inhibitory neurons and astrocytic cells to these behaviors remains unknown.
