Background And Aim: We recently identified protein kinase N1 (PKN1) as a master regulator of brain development. However, its function in the adult brain has not been clearly established. In this study, we assessed the cerebral energetic phenotype of wildtype (WT) and global Pkn1 knockout (Pkn1) animals under physiological and pathophysiological conditions.

Objective: Glucose-1,6-bisphosphate (G-1,6-BP), a byproduct of glycolysis that is synthesized by phosphoglucomutase 2 like 1 (PGM2L1), is particularly abundant in neurons. G-1,6-BP is sensitive to the glycolytic flux, due to its dependence on 1,3-bisphosphoglycerate as phosphate donor, and the energy state, due to its degradation by inosine monophosphate-activated phosphomannomutase 1. Since the exact role of this metabolite remains unclear, our aim was to elucidate the specific function of G-1,6-BP in the brain.

Article Synopsis
  • - Chronic hepatitis B virus (HBV) infection affects 300 million people globally, leading to dysfunction in virus-specific CD8 T cells that struggle to eliminate HBV-infected liver cells due to mechanisms that aren't fully understood.
  • - Research indicates a liver immune rheostat inhibits the activation of these CD8 T cells, particularly the CXCR6 subtype, leading to loss of their functionality, as shown by increased activity of the transcription factor cAMP-responsive element modulator (CREM) in both experimental models and chronic HBV patients.
  • - Enhanced signaling pathways related to cAMP and protein kinase A (PKA) in these T cells contribute to their dysfunction, as they establish prolonged contacts with liver cells, impairing essential activation

Article Synopsis
  • Researchers studied the role of PKD3, a member of the Protein kinases D family, in T cell responses, particularly how it differs from the better-understood PKD2.
  • Using a mouse model that overexpresses PKD3 in T cells, they found an increase in central memory T cells, though this was not fully explained by lab tests and seemed tied to developmental changes during thymic development.
  • Ultimately, they concluded that PKD3 plays a subtle role in shaping the development of central memory and CD8 T cells, but it doesn't significantly affect overall immune responses in specific tests.

Hypersynchronous (HYP) seizure onset is one of the frequently observed seizure-onset patterns in temporal lobe epileptic animals and patients, often accompanied by hippocampal sclerosis. However, the exact mechanisms and ion dynamics of the transition to HYP seizures remain unclear. Transcranial magneto-acoustic stimulation (TMAS) has recently been proposed as a novel non-invasive brain therapy method to modulate neurological disorders.
