Beneficial effects of leptin on obesity, T cell hyporesponsiveness, and neuroendocrine/metabolic dysfunction of human congenital leptin deficiency

The leptin-deficient ob/ob mouse presents with a multitude of phenotypic abnormalities including severe obesity, infertility, immune system dysfunction and limited growth - all reversible following subcutaneous leptin administration. Much less is known about human leptin deficiency. I. Sadaf Farooqi and colleagues previously reported on 2 children with congenital leptin deficiency suffering from hyperphagia and severe obesity. These conditions were reduced following 1 year of subcutaneous recombinant human leptin therapy in the older subject. The authors now report (on pages 1093-1103) on the status of these two children, as well as a third, after up to 50 months of chronic r-metHuLeptin therapy. Treatment induced a decrease in caloric intake and fat mass (while lean mass increased in keeping with increased linear growth). Surprisingly, the basal metabolic rate in all subjects remained unchanged and allowed appropriately timed pubertal development. Reversal of severely impaired lymphocyte function suggests that leptin is a key molecule in both CD4+ T cell development and function and raises the possibility of leptin-replacement therapy for other immunodeficiencies.

CCL25 mediates the localization of recently activated CD8ab+ lymphocytes to the small-intestinal mucosa

Given the continuous exposure of the intestine to foreign antigens, it is not surprising that large numbers of T lymphocytes are recruited from the blood to the intestine. In addition to lymphocytic expression of adhesion molecules that direct lymphocyte migration from the blood into intestinal tissues, evidence is mounting that chemokines and their receptors may also be involved. On pages 1113-1121 William Agace and colleagues demonstrate that expression of the chemokine receptor CCR9 is selectively maintained on CD8+ T cells activated in murine gut-associated lymphoid tissues and that neutralization of the CCR9 ligand CCL25 with a blocking antibody inhibits the accumulation of these cells in the small intestinal epithelial compartment. These results provide direct in vivo demonstration of a functional role for a chemokine/receptor pair in lymphocyte localization to the intestinal mucosa.

Neutrophil-independent mechanisms of caspase-1- and IL-18-mediated ischemic acute tubular necrosis in mice

Acute tubular necrosis is the predominant pathological process in animal models of ischemic acute renal failure (ARF) and in post-transplantation ARF in humans. Caspase proteases are involved in apoptotic as well as necrotic cell death, and several lines of evidence suggest that caspases play a role in ischemic ARF in mice. Charles Edelstein and colleagues have previously shown that mice lacking proinflammatory caspase-1 are protected from ischemic ARF and that this is (at least in part) due to lack of caspase activation of IL-18. The caspase-1 knockout mice also show less neutrophil infiltration. In a new set of experiments (pages 1083-1091), the researchers tested the potential of a new caspase inhibitor to protect against ischemic ARF and further examined the role of neutrophils in damage to the kidney. The experiments demonstrated efficacy of the drug in mice and revealed a novel mechanism of IL-18-mediated renal toxicity that acts independently of neutrophils.
