Dr. James B. Sidbury, Jr. passed away in Mount Vernon, Washington on February 17, 2003. He was the Scientific Director of the National Institute of Child Health and Human Development (NICHD), of the National Institutes of Health (NIH) from 1975 to 1981 and remained at the NICHD as a Scientist Emeritus until a year before his death. We were very fortunate to have him serve as an Associate Editor of Current Molecular M Read More

Recent experiments have unravelled novel signal transduction pathways that involve the SRC homology 2 (SH2) domain adapter protein SHB. SHB is ubiquitously expressed and contains proline rich motifs, a phosphotyrosine binding (PTB) domain, tyrosine phosphorylation sites and an SH2 domain and serves a role in generating signaling complexes in response to tyrosine kinase activation. SHB mediates certain responses in platele Read More

Obesity has become a worldwide public health problem affecting millions of people. A disruption of the balance between energy intake and energy expenditure is believed to be the major cause of obesity. Substantial progress has been made in deciphering the pathogenesis of energy homeostasis over the past few years. The fact that obesity is under strong genetic control has been well established. Human monogenic Read More

The human γ-herpesvirus Epstein-Barr virus establishes latent, life-long infection in more than 95% of the human adult population. Despite its growth transforming capacity, most carriers control EBV associated malignancies efficiently and remain free of EBV+ tumors. It is commonly accepted that lymphoblastoid cells, expressing all EBV latent antigens, are targeted by the immune system and cause tumors only in im Read More

Bulimia nervosa (BN) and Anorexia Nervosa (AN) are currently classified as eating disorders (ED). Both disorders are the product of complex interaction between physiological and psychological and social processes; they are characterized by abnormal eating behavior. However, patients with BN differ from AN in their nutritional state and response of treatment with serotonin-selective reuptake inhibitor (SSRI) as well as fr Read More

Significant advances have been made over the past few years concerning the cellular and molecular events underlying ischemic cell death. The brain succumbs to ischemic injury as a result of loss of metabolic stores, excessive intracellular calcium accumulation, oxidative stress, and potentiation of the inflammatory response. Neurons can also die via necrotic or apoptotic mechanisms, depending on the nature and se Read More

Higher animals establish host defense by orchestrating innate and adaptive immunity. This is mediated by professional antigen presenting cells, i.e. dendritic cells (DCs). DCs can incorporate pathogens, produce a variety of cytokines, maturate, and present pathogen-derived peptides to T cells, thereby inducing T cell activation and differentiation. These responses are triggered by microbial recognition through type I transmembr Read More

Leukocyte recruitment to sites of inflammation, infection or vascular injury is a complex event, depending on a tightly coordinated sequence of leukocyte-endothelial- and leukocyte-platelet interactions, which are controlled by the expression and activation of various adhesion receptors and protease systems. The present review will focus on novel aspects of the regulation of integrindependent leukocyte adhesion by haemost Read More
