Causes, consequences, and reversal of immune system aging

TLDR
The effects of aging on the immune system are manifest at multiple levels that include reduced production of B and T cells in bone marrow and thymus and diminished function of mature lymphocytes in secondary lymphoid tissues, and elderly individuals do not respond to immune challenge as robustly as the young.
Abstract
The effects of aging on the immune system are manifest at multiple levels that include reduced production of B and T cells in bone marrow and thymus and diminished function of mature lymphocytes in secondary lymphoid tissues. As a result, elderly individuals do not respond to immune challenge as robustly as the young. An important goal of aging research is to define the cellular changes that occur in the immune system and the molecular events that underlie them. Considerable progress has been made in this regard, and this information has provided the rationale for clinical trials to rejuvenate the aging immune system.

Performance Characteristics of the Abbott Architect SARS-CoV-2 IgG Assay and Seroprevalence in Boise, Idaho.

TL;DR: It is expected that the availability of high-quality serological testing will be a key tool in the fight against SARS-CoV-2 as the limited circulation of the virus in the western United States.

Unmasking senescence: context-dependent effects of SASP in cancer

TL;DR: This Review discusses the diverse effects of senescence and thesenescence-associated secretory phenotype (SASP) on tumour growth, focusing on the functional and sometimes opposing outputs of the SASP in stromal cells and incipient tumour cells.

The mitochondrial UPR: mechanisms, physiological functions and implications in ageing

TL;DR: The signal transduction mechanisms that regulate the UPRmt and the physiological consequences of its activation that affect cellular and organismal health during ageing are discussed.

Mortality Associated With Influenza and Respiratory Syncytial Virus in the United States

TL;DR: Mortality associated with both influenza and RSV circulation disproportionately affects elderly persons, and influenza deaths have increased substantially in the last 2 decades, in part because of aging of the population, highlighting the need for better prevention measures, including more effective vaccines and vaccination programs for elderly persons.

The Senescence-Associated Secretory Phenotype: The Dark Side of Tumor Suppression

TL;DR: A senescence-associated secretory phenotype (SASP) is acquired that turns senescent fibroblasts into proinflammatory cells that have the ability to promote tumor progression.

Insulin and insulin-like growth factor signalling in neoplasia

TL;DR: Epidermiological, clinical and laboratory research methods are being used to investigate novel cancer prevention and treatment strategies related to insulin and IGF signalling, including the use of novel receptor-specific antibodies, receptor kinase inhibitors and AMP-activated protein kinase activators.
