Background: Childhood obesity predisposes to metabolic disorders. Low grade inflammation of adipose tissue (AT) associated with macrophage infiltration may lead to metabolic complications. Two macrophage activation states M1 (pro-inflammatory) and M2 (anti-inflammatory) exist in AT with surface markers CD40 (M1), CD206 (M2) and CD163 (M2). M1 polarization correlates with metabolic complications.Objective and hypotheses: To study the expression of CD40, C...

Background: Morbid childhood obesity predisposes to metabolic disorders such as diabetes type 2. In mice, heat-producing ‘brown-like’ (beige) adipocytes can suppress weight gain and metabolic disease through the action of uncoupling protein 1 (UCP1) localized in the mitochondria.Objective and hypotheses: To study the expression of UCP1 in the adipose tissue of lean&obese children and adolescents.Method: Paraffin embed...

Background: Adipose tissue (AT) in obesity is characterized by low grade inflammation. The apoptosis inhibitor of macrophages (AIM; also called CD5L) is incorporated into adipocytes leading to increased lipolysis. Excess AIM-dependent lipolysis induces adipose tissue macrophage recruitment. M1 (proinflammatory) macrophage infiltration, with surface marker CD40, correlates with metabolic complications.Objective and hypotheses: To study serum levels and AT...

Objective: AMH causes fetal paramesonephric duct regression and is involved in testicular development and function. Sertoli cell AMH remains high during childhood until puberty. The appendix testis (AT), a remnant of the paramesonephric duct, contains both androgen and estrogen receptors. AT androgen receptors have been reported to play a role in embryonic testicular descent. The AT is commonly resected during orchiopexy and abdominal surgery as possible torsion in the future ...
