Antimicrobial peptides are present in most living species and constitute important effector molecules of innate immunity. Recently, we and others have detected antimicrobial peptides in the brain. This is an organ that is rarely infected, which has mainly been ascribed to the protective functions of the blood-brain barrier (BBB) and meninges. Since the(More)
Pathogenic bacteria have evolved numerous mechanisms to evade the human immune system and have developed widespread resistance to traditional antibiotics. We studied the human pathogen Neisseria meningitidis and present evidence of novel mechanisms of resistance to the human antimicrobial peptide LL-37. We found that bacteria attached to host epithelial(More)
The ScpC protease of Streptococcus pyogenes degrades interleukin-8 (IL-8), a chemokine that mediates neutrophil transmigration and activation. The ability to degrade IL-8 differs dramatically among clinical isolates of S. pyogenes. Bacteria expressing ScpC overcome immune clearance by preventing the recruitment of neutrophils in soft tissue infection of(More)
To investigate changes in gene expression associated with ERBB2, expression profiling of immortalized human mammary luminal epithelial cells and variants expressing a moderate and high level of ERBB2 has been carried out using cDNA microarrays corresponding to approximately 6000 unique genes/ESTs. A total of 61 significantly up- or downregulated (2.0-fold)(More)
Pathogenic bacteria can modulate and interfere with human cell cycle progression. Here we study the human pathogen Neisseria gonorrhoeae and its ability to influence and affect the cell cycle in two human target cell lines. We found that bacteria adhere equally well to cells synchronized into the different cell cycle phases of G1, S, and G2, but were unable(More)
Self-focused attention refers to attention consciously directed toward the self. Although cognitive models of panic posit the importance of attending to internal sensations and the role of this self-focus in the experience and maintenance of panic, limited empirical work has examined self-focus in the anxiety disorders. The current investigation examines(More)
Based on experimental observations that verapamil and tamoxifen reverse multiple drug resistance, the authors investigated the feasibility of combining both agents with the initial chemotherapy of extensive small cell lung cancer. Overall, in a consecutive series of 58 patients the most important toxicity was myelosuppression, and there was a 24% rate of(More)
