Leptin in pregnancy and development: a contributor to adulthood disease?
Emerging research has highlighted the importance of leptin in fetal growth and development independent of its essential role in the maintenance of hunger and satiety through the modulation of neuropeptide Y and proopiomelanocortin neurons. Alterations in maternal-placental-fetal leptin exchange may modify the development of the fetus and contribute to the increased risk of developing disease in adulthood. In addition, leptin also plays an important role in reproductive functions, with plasma leptin concentrations rising in pregnant women, peaking during the third trimester. Elevated plasma leptin concentrations occur at the completion of organogenesis, and research in animal models has demonstrated that leptin is involved in the development and maturation of a number of organs, including the heart, brain, kidneys, and pancreas. Elevated maternal plasma leptin is associated with maternal obesity, and reduced fetal plasma leptin is correlated with intrauterine growth restriction. Alterations in plasma leptin during development may be associated with an increased risk of developing a number of adulthood diseases, including cardiovascular, metabolic, and renal diseases via altered fetal development and organogenesis. Importantly, research has shown that leptin antagonism after birth significantly reduces maturation of numerous organs. Conversely, restoration of the leptin deficiency after birth in growth-restricted animals restores the offspring's body weight and improves organogenesis. Therefore, leptin appears to play a major role in organogenesis, which may adversely affect the risk of developing a number of diseases in adulthood. Therefore, greater understanding of the role of leptin during development may assist in the prevention and treatment of a number of disease states that occur in adulthood.

Weight in the balance.
The adage 'we are what we eat' is taking on a new meaning in our well-fed and increasingly sedentary culture, as many of us convert much of our excess food into body fat; in the USA, 60% of the population is now considered to be overweight. Obesity brings with it an increased risk of developing type II diabetes, hypertension and heart disease, so the mechanisms that control food intake and body weight are of considerable importance for public health and clinical medicine. The mass of body fat is now known to be regulated by several hormones and neuropeptides. Two of these, the circulating peptide hormones leptin and ghrelin have actions that include reciprocal effects on appetite-regulating neurons in the hypothalamus. This article reviews data discussed at a recent meeting(1), where an overview of recent developments in research into leptin and ghrelin was presented. Topics covered are the roles of leptin and ghrelin in the regulation of food intake and energy production; the integration of food intake with other energy-regulated processes, such as growth, sexual maturation and reproduction, sleep and the immune response; and pathological conditions, ranging from diabetes to psychiatric disorders.1 This report summarizes conclusions of the meeting 'Brain Somatic Cross-Talk and the Central Metabolism' held in Paris on January 28, 2002.
