Inflammaging? Blame T cells!
Mitochondrial dysfunction in various tissues is a prominent characteristic of age-related deterioration, but it is unclear how mitochondrial dysfunction in particular cell types contributes to this process. Desdín-Micó et al. generated mice with T cells that were specifically deficient in a mitochondrial DNA–stabilizing...
Mitochondria fulfill important and diverse roles during the different stages of T cell adaptive responses. Here we discuss the role of the mitochondria in T cells from the initial steps of activation at the immune synapse to their participation in memory responses and T cell exhaustion. Mitochondria are relocated to the immune synapse in order to s...
When T cells are exposed to continuous antigen stimulation, they become exhausted. Here, we preview findings from Scharping et al. (2021), who have illuminated the molecular mechanism by which the persistent antigen stimulation and severe hypoxic conditions in the intratumoral environment drive T cell exhaustion, losing their cytotoxic function and...
Background: Marfan syndrome (MFS) is an autosomal dominant disorder of the connective tissue caused by mutations in the FBN1 gene encoding a large glycoprotein in the extracellular matrix called fibrillin-1. The major complication of this connective disorder is the risk to develop thoracic aortic aneurysm (TAA). To date, no effective pharmacologica...
Different microRNAs (miRNAs), including miR-29 family, may play a role in the development of heart failure (HF), but the underlying molecular mechanisms in HF pathogenesis remain unclear. We aimed at characterizing mice deficient in miR-29 in order to address the functional relevance of this family of miRNAs in the cardiovascular system and its con...
Aging is the major risk factor for most human diseases and represents a major socio-economical challenge for modern societies. Despite its importance, the process of aging remains poorly understood. Epigenetic dysregulation has been proposed as a key driver of the aging process. Modifications in transcriptional networks and chromatin structure migh...
Age-associated neurodegenerative disorders represent significant challenges due to progressive neuronal decline and limited treatments. In aged mice, partial reprogramming, characterized by pulsed expression of reprogramming factors, has shown promise in improving function in various tissues, but its impact on the aging brain remains poorly underst...
In vivo reprogramming through the forced expression of Oct4, Sox2, Klf4, and c-Myc (OSKM) has demonstrated great potential for reversing age-associated phenotypes, as the combination of these transcription factors actively promote cell regeneration and rejuvenation in various tissues and organs. However, continuous in vivo OSKM expression raised sa...
The induction of cellular reprogramming via expression of the transcription factors Oct4, Sox2, Klf4 and c‐Myc (OSKM) can drive dedifferentiation of somatic cells and ameliorate age-associated phenotypes in multiple tissues and organs. However, the benefits of long-term in vivo reprogramming are limited by detrimental side‐effects. Here, using comp...
Unlike aged somatic cells, which exhibit a decline in molecular fidelity and eventually reach a state of replicative senescence, pluripotent stem cells can indefinitely replenish themselves while retaining full homeostatic capacity. The conferment of beneficial-pluripotency related traits via in vivo partial cellular reprogramming (IVPR) significan...
The induction of cellular reprogramming by forced expression of the transcription factors OCT4, SOX2, KLF4, and C-MYC (OSKM) has been shown to allow the dedifferentiation of somatic cells and ameliorate age-associated phenotypes in multiple tissues and organs. Yet to date, the benefits of in vivo reprogramming are limited by the occurrence of detri...
Age-related T cell dysfunction can lead to failure of immune tolerance mechanisms, resulting in aberrant T cell-driven cytokine and cytotoxic responses that ultimately cause tissue damage. In this Review, we discuss the role of T cells in the onset and progression of age-associated conditions, focusing on cardiovascular disorders, metabolic dysfunc...
Due to their ability to shuttle proteins, lipids and genetic material between distant cells, exosomes promote extensive phenotypic changes in recipient cells, modulating immune responses, cellular migration, cancer metastasis or the spreading of neurotoxic protein aggregates in neurodegenerative diseases. Besides intercellular communication, exosom...
