[The guidelines of the Federal Joint Committee on acute pain management : Background and consequences for the practice in hospitals].

The quality of postoperative pain therapy in Germany shows a heterogeneous treatment practice and large differences in quality between individual institutions, The patient representatives in the Federal Joint Committee (G-BA) have therefore decisively campaigned for many years that instruments of non-legislative standards are employed in order to noticeably improve the quality of perioperative pain therapy for patients in Germany. As a result of these efforts, in October 2020 a binding specification for internal quality management was included in the quality management guidelines (QM-RL) by the G‑BA. This describes in concrete terms the structural and procedural requirements for an internal quality management of acute pain for all institutions in which operations and comparable potentially painful interventions are carried out.

Puma, but not noxa is essential for oligodendroglial cell death.

The mechanisms involved in oligodendroglial cell death in human demyelinating diseases are only partly understood. Here, we demonstrate that the BH3 only protein Puma, but not Noxa, is essential for oligodendroglial cell death in toxic demyelination induced by the copper chelator cuprizone. Primary oligodendrocytes derived from Noxa- or Puma-deficient mice showed comparable differentiation to wild-type cells, but Puma-deficient oligodendrocytes were less susceptible to spontaneous, staurosporine, or nitric oxide-induced cell death.

c-Jun controls histone modifications, NF-kappaB recruitment, and RNA polymerase II function to activate the ccl2 gene.

Interleukin-1 (IL-1)-induced mRNA expression of ccl2 (also called MCP-1), a prototypic highly regulated inflammatory gene, is severely suppressed in cells lacking c-Jun or Jun N-terminal protein kinase 1 (JNK1)/JNK2 genes and is only partially restored in cells expressing a c-Jun(SS63/73AA) mutant protein. We used chromatin immunoprecipitation to identify three c-Jun-binding sites located in the far 5' region close to the transcriptional start site and in the far 3' region of murine and human ccl2 genes. Mutational analysis revealed that the latter two sites contribute to ccl2 transcription in response to the presence of IL-1 or of ectopically expressed c-Jun-ATF-2 dimers.

Transcriptional regulation of EGR-1 by the interleukin-1-JNK-MKK7-c-Jun pathway.

The proinflammatory cytokine interleukin (IL)-1 activates several hundred genes within the same cell. This occurs in part by activation of the MKK7-JNK-c-Jun signaling pathway whose precise role in the regulation of individual inflammatory genes is still incompletely understood. To identify the genes that are under specific control of activated JNK, we used a JNK-MKK7 fusion protein.

Simultaneous blockade of NFkappaB, JNK, and p38 MAPK by a kinase-inactive mutant of the protein kinase TAK1 sensitizes cells to apoptosis and affects a distinct spectrum of tumor necrosis factor [corrected] target genes.

The inflammatory response is characterized by the induction (or repression) of hundreds of genes. The activity of many of these genes is controlled by MAPKs and the IkappaB kinase-NFkappaB pathway. To reveal the effects of blocking these pathways simultaneously, fibroblasts were infected with retroviruses encoding TAK1K63W, an inactive mutant of the protein kinase TAK1.

MEK1-dependent delayed expression of Fos-related antigen-1 counteracts c-Fos and p65 NF-kappaB-mediated interleukin-8 transcription in response to cytokines or growth factors.

Binding sites for the dimeric transcription factor activator protein (AP)-1 are found in numerous immunoregulatory and inflammatory genes. The precise mechanisms by which AP-1 activates or represses immune response genes and in particular the roles of individual AP-1 subunits in inflammatory responses are largely unknown. We report here that c-Fos and Fos-related antigen-1 (Fra-1), two inducible components of AP-1, are recruited to the endogenous interleukin (IL)-8 promoter in an IL-1-dependent manner.

Constitutive and interleukin-1-inducible phosphorylation of p65 NF-{kappa}B at serine 536 is mediated by multiple protein kinases including I{kappa}B kinase (IKK)-{alpha}, IKK{beta}, IKK{epsilon}, TRAF family member-associated (TANK)-binding kinase 1 (TBK1), and an unknown kinase and couples p65 to TATA-binding protein-associated factor II31-mediated interleukin-8 transcription.

Phosphorylation of NF-kappaB p65(RelA) serine 536 is physiologically induced in response to a variety of proinflammatory stimuli, but the responsible pathways have not been conclusively unraveled, and the function of this phosphorylation is largely elusive. In contrast to previous studies, we found no evidence for a role of c-Jun N-terminal kinase, p38 kinase, extracellular signal-regulated kinase, or phosphatidylinositol 3-kinase in interleukin-1- or tumor necrosis factor-induced Ser-536 phosphorylation, as revealed by pharmacological inhibitors. We were not able to suppress Ser-536 phosphorylation by either RNA interference directed at IkappaB kinase (IKK)-alpha/beta (the best characterized Ser-536 kinases so far) or the IKKbeta inhibitor SC-514 or dominant negative mutants of either IKK.

Streptococcus pneumoniae-induced p38 MAPK-dependent phosphorylation of RelA at the interleukin-8 promotor.

Streptococcus pneumoniae is the major cause of community-acquired pneumonia and one of the most common causes of death by infectious disease in industrialized countries. Little is known concerning the mechanisms of target cell activation in this disease. The present study shows that NF-kappaB and p38 MAPK signaling pathways contribute to chemokine synthesis by lung epithelial cells in response to pneumococci.

A century of population aging in Germany.

The population of Germany is becoming progressively more elderly, and this article focuses on the causes and implications of that trend. We discuss the demographic processes that occurred in Germany in the second half of the 20th century and describe the developments that the population of Germany will undergo in the next 50 years, which promise to exert a profound influence on the economic and social future of the country.

Activation of NF-kappaB and IL-8 by Yersinia enterocolitica invasin protein is conferred by engagement of Rac1 and MAP kinase cascades.

Yersinia enterocolitica triggers activation of the nuclear factor (NF)-kappaB and production of the proinflammatory chemokine interleukin (IL)-8 in intestinal epithelial cells. This activation is due to adhesion of the bacteria via their outer membrane protein invasin to the host cells. Using Clostridium difficile toxins that specifically inactivate small GTPases, and transfection of inhibitory proteins of the Rho-GTPases, we demonstrate that Rac1, but not Cdc42 or Rho, is required for activation of NF-kappaB by invasin.

Disruption of the c-JUN-JNK complex by a cell-permeable peptide containing the c-JUN delta domain induces apoptosis and affects a distinct set of interleukin-1-induced inflammatory genes.

The transcription factor activator protein (AP)-1 plays crucial roles in proliferation, cell death, and the immune response. c-JUN is an important component of AP-1, but only very few c-JUN response genes have been identified to date. Activity of c-JUN is controlled by NH2-terminal phosphorylation (JNP) of its transactivation domain by a family of JUN-NH2-terminal protein kinases (JNK).

Multiple control of interleukin-8 gene expression.

Interleukin (IL)-8, a prototypic human chemokine, was detected more than a decade ago as the founding member of the chemokine superfamily. One of the most remarkable properties of IL-8 is the variation of its expression levels. In healthy tissues, IL-8 is barely detectable, but it is rapidly induced by ten- to 100-fold in response to proinflammatory cytokines such as tumor necrosis factor or IL-1, bacterial or viral products, and cellular stress.
