Gene Transcription Through Activation of G-Protein-Coupled Chemoattractant Receptors
Receptors for leukocyte chemoattractants, including chemokines, are traditionally considered to be responsible for the activation of special leukocyte functions such as chemotaxis, degranulation, and the release of superoxide anions. Recently, these G-protein-coupled serpentine receptors have been found to transduce signals leading to gene transcription and translation in leukocytes. Transcription factors, such as NFκB and AP-1, are activated upon stimulation of the cells with several chemoattractants at physiologically relevant concentrations. Activation of transcription factors through these receptors involves Gprotein coupling and the activation of protein kinases. The underlying signaling pathways appear to be different from those utilized by TNF-α, a better characterized cytokine that induces the transcription of immediate-early genes. Chemoattractants stimulate the expression of several inflammatory cytokines and chemokines, which in turn may activate their respective receptors and initiate an autocrine regulatory mechanism for persistent cytokine and chemokine gene expression.

- Gene Expression, The Journal of Liver Research will publish articles in all aspects of hepatology. Hepatology, as a research discipline, has seen unprecedented growth especially in the cellular and molecular mechanisms of hepatic health and disease, which continues to have a major impact on understanding liver development, stem cells, carcinogenesis, tissue engineering, injury, repair, regeneration, immunology, metabolism, fibrosis, and transplantation. Continued research and improved understanding in these areas will have a meaningful impact on liver disease prevention, diagnosis, and treatment. The existing journal Gene Expression has expanded its focus to become Gene Expression, The Journal of Liver Research to meet this growing demand. In its revised and expanded scope, the journal will publish high-impact original articles, reviews, short but complete articles, and special articles (editorials, commentaries, opinions) on all aspects of hepatology, making it a unique and invaluable resource for readers interested in this field. The expanded team, led by an Editor-in-Chief who is uniquely qualified and a renowned expert, along with a dynamic and functional editorial board, is determined to make this a premier journal in the field of hepatology.
