AI Article Synopsis

  • White and brown adipose tissues are responsive to environmental changes and regulated by circadian rhythms, which help anticipate these changes.
  • Circadian disturbances, common in our 24/7 lifestyles, increase the risk of cardiovascular and metabolic diseases.
  • This review explores ways to reduce disease risk associated with these disturbances and highlights potential strategies like chronotherapy and identifying new therapeutic targets to enhance treatment effectiveness.

Article Abstract

White and brown adipose tissues are highly dynamic organs anticipating and responding to changes in the environment. The circadian timing system facilitates anticipation, and it is therefore not surprising that circadian disturbances, a prominent feature of modern 24/7 society, increase the risk for (cardio)metabolic diseases. In this mini-review, we will address mechanisms and strategies to mitigate disease risk associated with circadian disturbances. In addition, we discuss the opportunities arising from the knowledge we gained about circadian rhythms in these adipose tissues, including the application of chronotherapy, optimizing endogenous circadian rhythms to allow for more effective intervention, and the identification of novel therapeutic targets.

Skeletal muscles contain lipids inside and outside cells, namely intramyocellular lipids (IMCL) and extramyocellular lipids (EMCL), respectively; lipids have also been found to be interspersed between these muscles as adipose tissue, namely intermuscular adipose tissue (IMAT). Metabolized IMCL has been recognized as an important substrate for energy production and their metabolism is determined by the muscle oxidative capacity. Therefore, it has been speculated that muscle oxidative capacity is related to muscle lipid content.

The present study examined factors associated with trunk skeletal muscle thickness (MT, an index for the amount of skeletal muscle) and echo intensity (EI, an index for the content of non-contractile tissue, such as intramuscular adipose tissue) in young Japanese men and women in consideration of habitual dietary intake. Healthy men (n = 26) and women (n = 24) aged 20 to 26 were enrolled. Trunk MT and EI were evaluated using ultrasound imaging at the height of the 3rd lumbar vertebra.

Changes in the lipid and carbohydrate metabolism, adipokines, and growth factors during the development of metabolic disorders were studied in three mouse models: C57BL/6 (alimentary obesity), db/db (leptin-resistant obesity), and NOD (diabetes mellitus) lines. In the group of alimentary obesity, moderate fatty infiltration of the liver and hypertrophy of the adipose tissue, hyperglycemia, and increased concentrations of adiponectin, transforming growth factor β1 (TGF-β1), leptin, and cholesterol were detected. In the group of leptin-resistant obesity, multiple pathological changes in tissues, severe hyperglycemia and hyperleptinemia, hyperinsulinemia, and reduced concentrations of triglycerides, adiponectin, myostatin, and TGF-β1 were detected.

This study tested whether combined ceftriaxone and adipose-derived mesenchymal stem cells (ADMSCs) would defend the spinal cord against acute spinal infection (ASI) in rodent. Adult-Male-SD rats were grouped into groups 1 (SC)/2 (ASI)/3 (ASI + ceftriaxone from days 2 to 28 after ASI induction)/4 (ASI + allogenic ADMSCs from day 2 for a total of 3 doses/3 consecutive intervals by intravenous injection)/5 (ASI + combined ceftriaxone and ADMSC) and spinal cord tissues were harvested by day 28. Circulatory levels of TNF-α/IL-6 at days 7 and 28, and these two parameters in spinal fluid at day 28 were lowest in group 1, highest in group 2, significantly lower in group 5 than in groups 3/4, and significantly lower in group 3 than in group 4 (all p < 0.

Background: Immune-mediated inflammatory diseases (IMIDs) are a group of chronic conditions characterized by dysregulated immune responses and persistent inflammation. Rheumatoid arthritis (RA), spondyloarthritis (SpA), and ulcerative colitis (UC) exemplify prominent IMIDs, each presenting unique challenges for their management, that impact patient's quality of life (QoL). Obesity, marked by persistent low-grade inflammation, influences the progression, response to treatment, and clinical management of patients with RA, SpA, and UC.
