Neutrophils are the most abundant leukocytes in the blood, with numbers further increasing with age. Despite their essential role as a primary line of defense, neutrophils can contribute to tissue damage and age-related diseases 1 and a high neutrophil-to-lymphocyte ratio predicts all causes of mortality in the elderly 2–5. However, the precise mechanisms driving enhanced

Warburg Effect Reshapes Tumor Immunogenicity.

José A Enríquez , María Mittelbrunn

Tumor cells rewire their metabolism to fulfill the demands of highly proliferative cells. This changes cellular metabolism to adapt to fuel and oxygen availability for energy production and to increase the synthesis capacity of building blocks for cell division and growth. In addition, the metabolic shift modulates the immunogenicity of the tumor cells. Recently, Mahmood

The mysteries behind immune aging and its related inflammation are being unmasked. Jin et al. reveal that the defective turnover of damaged mitochondria in CD4+ T cells from older individuals results in the exacerbated secretion of mitochondrial DNA, which fuels inflammaging and impairs immune
