Global levels of obesity are reaching epidemic proportions, leading to a dramatic increase in incidence of secondary diseases and the significant economic burden associated with their treatment. These comorbidities include diabetes, cardiovascular disease, and some psychopathologies, which have been linked to a low-grade inflammatory state. Obese individuals exhibit an increase in circulating inflammatory mediators implicated as the underlying cause of these comorbidities. A number of these molecules are also manufactured and released by white adipose tissue (WAT), in direct proportion to tissue mass and are collectively known as adipokines. In the current review we focused on the role of two of the better-studied members of this family namely, leptin and adiponectin, with particular emphasis on their role in neuro-immune interactions, neuroinflammation and subsequent brain diseases. This article is part of a Special Issue entitled 'Neuroimmunology and Synaptic Function'.

Adipokines and Transitions in Metabolic Health Over Time: The Atherosclerosis Risk In Communities (ARIC) Study.
J Clin Endocrinol Metab
January 2025
Division of Cardiology, Department of Medicine, School of Medicine, Johns Hopkins University, Baltimore, MD, USA.
Context: Transitions in metabolic health status over time are strongly linked to risk for cardiovascular events, particularly among individuals with obesity. Adipokines are proteins with metabolic effects, but their role in transitions in metabolic health status over time is unknown.
Objective: To evaluate the associations of adiponectin and leptin with metabolic risk transitions over time.
Obesity is a metabolic disease that is marked by excessive fat accumulation and is objectively defined as a body mass index (BMI) ≥30 kg/m2. Obesity is associated with several other comorbidities, including psoriasis, which is a chronic autoimmune skin disease. Adipocytes produce pro-inflammatory signaling molecules, namely adipokines and classic cytokines, that drive increased inflammation axnd may contribute to the pro-inflammatory pathways driving psoriasis disease pathogenesis.

Article Synopsis
- The study examined lipid and carbohydrate metabolism as well as adipokines and growth factors in three mouse models with different metabolic disorders: alimentary obesity, leptin-resistant obesity, and diabetes mellitus.
- In the alimentary obesity model, mice showed moderate liver fat, enlarged adipose tissue, and elevated levels of glucose, adiponectin, and cholesterol.
- In the leptin-resistant model, severe tissue issues were noted, along with high blood sugar and leptin but low triglycerides and certain growth factors.
- The diabetes mellitus model revealed a decrease in insulin-producing cells and lower levels of important hormones like adiponectin and leptin, along with high insulin levels.
Obesity and Chronic Inflammation: Implications for Rheumatoid Arthritis, Spondyloarthritis, and Ulcerative Colitis.
Immun Inflamm Dis

IBD Unit, IRCCS Sacro Cuore Don Calabria, Negrar, Italy.
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.

Background: Research into the mechanisms of growth control during birth and postnatal life has shown that adipose tissue regulates many physiological functions in the body by secreting adipokines. The aims of this study were to investigate the serum levels of visfatin and vaspin in healthy and unhealthy pregnant women and its relationship with their newborns' anthropometric measurements.
Materials And Methods: A total of 82 pregnant women were included in this study with their respective newborn) healthy pregnant women (n = 30), with obesity (n = 26) and with gestational diabetes (GD) (n = 26).
