Inflamaging is a chronic, low-grade inflammation that occurs due to a disruption in the regulation of the immune system during the aging process. This condition is associated with an increased risk of age-related illnesses, such as cardiovascular disease, neurodegenerative conditions, and metabolic disorders. Transcription factor NF-κB is one of the primary regulators of innate and adaptive immune responses, and its activation leads to the production of pro-inflammatory cytokines and chemokines that contribute to inflamaging. Understanding the age-related alterations in the levels of proteins from the NF-κB family will help us to better comprehend the mechanisms underlying inflamaging and develop more effective treatments for chronic inflammation. The quantification of this biomolecule in lymphocytes and oral epithelial cells could serve as a basis for a minimally invasive screening test for inflamaging diagnosis.

Objective: To assess the functional state and age-related characteristics of autophagy in peripheral blood leukocytes as a risk factor for the development of inflammaging using the example of the servicemen of the DefenseForces of Ukraine and clean-up workers of the Chornobyl accident.
Materials And Methods: A total of 103 male patients aged 28-77 (56,48 ∓ 9,05) years were examined. They included: the main group - 23 servicemen of the Defense Forces of Ukraine aged 44-59 (50,21 ∓ 5,13) years; the comparison group - 57 clean-up workers of the Chornobyl accident aged 56-63 (60,31 ∓ 1,78) years; and the control group -23 civilians aged 28-77 (53,26 ∓ 15,98) years.

Structural, functional, and molecular-level changes in the aging heart are influenced by a dynamic interplay between immune signaling and cellular metabolism that is referred to as immunometabolism. This review explores the crosstalk between cellular metabolic pathways including glycolysis, oxidative phosphorylation, fatty acid metabolism, and the immune processes that govern cardiac aging. With a rapidly aging population that coincides with increased cardiovascular risk and cancer incidence rates, understanding the immunometabolic underpinnings of cardiac aging provides a foundation for identifying therapeutic targets to mitigate cardiac dysfunction.

Low-grade chronic inflammation without obvious infection is defined as "inflammageing" and a key driver of skin ageing. Although the importance of modulating inflammageing for treating skin diseases and restoring cutaneous homeostasis is increasingly being recognized. However, the mechanisms underlying skin inflammageing, particularly those associated with natural treatments, have not been systematically elucidated.

Objectives: To determine how the anti-inflammatory actions of interleukin-10 (IL-10) and IL-6 differ across age and physical activity levels.
Methods: Using a cross-sectional design, fasted blood samples were obtained from younger physically inactive (YI: n=10, age: 22.7 ± 3.

Individuals with homozygous laminA/C p.R527C mutations manifest a severe form of Mandibuloacral dysplasia-(MAD) and exhibit overlapping progeroid symptoms, for which the underlying molecular pathology remains unknown. Herein, it is shown that MAD patients achieved inflammaging with different pro-inflammatory cytokines compared to progeria-(HGPS) patient.
