Defining Host Responses during Systemic Bacterial Infection through Construction of a Murine Organ Proteome Atlas.

ABSTRACT: Group A Streptococcus (GAS) remains one of the top 10 deadliest human pathogens worldwide despite its sensitivity to penicillin. Although the most common GAS infection is pharyngitis (strep throat), it also causes life-threatening systemic infections. A series of complex networks between host and pathogen drive invasive infections, which have not been comprehensively mapped. Attempting to map these interactions, we examined organ-level protein dynamics using a mouse model of systemic GAS infection. We quantified over 11,000 proteins, defining organ-specific markers for all analyzed tissues. From this analysis, an atlas of dynamically regulated proteins and pathways was constructed. Through statistical methods, we narrowed organ-specific markers of infection to 34 from the defined atlas. We show these markers are trackable in blood of infected mice, and a subset has been observed in plasma samples from GAS-infected clinical patients. This proteomics-based strategy provides insight into host defense responses, establishes potentially useful targets for therapeutic intervention, and presents biomarkers for determining affected organs during bacterial infection.

Project description:Clostridium difficile is a leading cause of antibiotic-associated diarrhea, a significant animal pathogen, and a worldwide public health burden. Most disease-causing strains secrete two exotoxins, TcdA and TcdB, which are considered to be the primary virulence factors. Understanding the role that these toxins play in disease is essential for the rational design of urgently needed new therapeutics. However, their relative contributions to disease remain contentious. Using three different animal models, we show that TcdA(+) TcdB(-) mutants are attenuated in virulence in comparison to the wild-type (TcdA(+) TcdB(+)) strain, whereas TcdA(-) TcdB(+) mutants are fully virulent. We also show for the first time that TcdB alone is associated with both severe localized intestinal damage and systemic organ damage, suggesting that this toxin might be responsible for the onset of multiple organ dysfunction syndrome (MODS), a poorly characterized but often fatal complication of C. difficile infection (CDI). Finally, we show that TcdB is the primary factor responsible for inducing the in vivo host innate immune and inflammatory responses. Surprisingly, the animal infection model used was found to profoundly influence disease outcomes, a finding which has important ramifications for the validation of new therapeutics and future disease pathogenesis studies. Overall, our results show unequivocally that TcdB is the major virulence factor of C. difficile and provide new insights into the host response to C. difficile during infection. The results also highlight the critical nature of using appropriate and, when possible, multiple animal infection models when studying bacterial virulence mechanisms.Clostridium difficile is a leading cause of antibiotic-associated diarrhea and an important hospital pathogen. TcdA and TcdB are thought to be the primary virulence factors responsible for disease symptoms of C. difficile infections (CDI). However, the individual contributions of these toxins to disease remain contentious. Using three different animal models of infection, we show for the first time that TcdB alone causes severe damage to the gut, as well as systemic organ damage, suggesting that this toxin might be responsible for MODS, a serious but poorly understood complication of CDI. These findings provide important new insights into the host response to C. difficile during infection and should guide the rational development of urgently required nonantibiotic therapeutics for the treatment of CDI.

Project description:The mitogen-activated protein kinase/extracellular signal-regulated kinase signaling pathway is an essential component of innate immunity necessary for mediating proinflammatory responses in the setting of sepsis. We previously demonstrated that the mitogen-activated protein kinase 1/2 inhibitor trametinib prevents endotoxin-induced renal injury in mice. We therefore assessed efficacy of trametinib in a more clinically relevant experimental model of sepsis.Controlled in vivo laboratory study.University animal research laboratory.Male C57BL/6 mice.Mice were subjected to cecal ligation and puncture to induce sepsis or underwent sham operation as controls. Six hours after cecal ligation and puncture, mice were randomized to four experimental groups as follows: 1) sham control; 2) sham control + trametinib (1?mg/kg, IP); 3) cecal ligation and puncture; and 4) cecal ligation and puncture + trametinib. All animals received buprenorphine (0.05?mg/kg, SC) and imipenem/cilastatin (14?mg/kg, SC) in 1.5?mL of warm saline (40?mL/kg) at the 6-hour time point. Mice were euthanized at 18 hours after induction of cecal ligation and puncture.Trametinib inhibition of mitogen-activated protein kinase/extracellular signal-regulated kinase signaling 6 hours after cecal ligation and puncture attenuated increases in circulating proinflammatory cytokines (tumor necrosis factor-?, interleukin-1?, interleukin-6, and granulocyte macrophage colony-stimulating factor) and hypothermia at 18 hours. Trametinib also attenuated multiple organ injury as determined by serum creatinine, alanine aminotransferase, lactate dehydrogenase, and creatine kinase. At the organ level, trametinib completely restored peritubular capillary perfusion in the kidney. Restoration of microvascular perfusion was associated with reduced messenger RNA expression of well-characterized markers of proximal tubule injury. mitogen-activated protein kinase/extracellular signal-regulated kinase blockade attenuated cecal ligation and puncture-mediated up-regulation of cytokines (tumor necrosis factor-?, interleukin-1?) and restored interleukin-6 to control levels in the renal cortex, indicating the protective effects on the proximal tubule occur primarily through modulation of the proinflammatory response in sepsis.These data reveal that the mitogen-activated protein kinase/extracellular signal-regulated kinase inhibitor trametinib attenuates systemic inflammation and multiple organ damage in a clinically relevant model of sepsis. Because trametinib has been safely used in humans, we propose that this drug might represent a translatable approach to limit organ injury in septic patients.

Project description:Reduced fat oxidation in hypertrophied hearts coincides with a shift of carnitine palmitoyl transferase I from muscle to increased liver isoforms. Acutely increased carnitine palmitoyl transferase I in normal rodent hearts has been shown to recapitulate the reduced fat oxidation and elevated atrial natriuretic peptide message of cardiac hypertrophy. Because of the potential for reduced fat oxidation to affect cardiac atrial natriuretic peptide, and thus, induce adipose lipolysis, we studied peripheral and systemic metabolism in male C57BL/6 mice model of transverse aortic constriction in which left ventricular hypertrophy occurred by 2 weeks without functional decline until 16 weeks (ejection fraction, -45.6%; fractional shortening, -22.6%). We report the first evidence for initially improved glucose tolerance and insulin sensitivity in response to 2 weeks transverse aortic constriction versus sham, linked to enhanced insulin signaling in liver and visceral adipose tissue (epididymal white adipose tissue [WAT]), reduced WAT inflammation, elevated adiponectin, mulitilocular subcutaneous adipose tissue (inguinal WAT) with upregulated oxidative/thermogenic gene expression, and downregulated lipolysis and lipogenesis genes in epididymal WAT. By 6 weeks transverse aortic constriction, the metabolic profile reversed with impaired insulin sensitivity and glucose tolerance, reduced insulin signaling in liver, epididymal WAT and heart, and downregulation of oxidative enzymes in brown adipose tissue and oxidative and lipogenic genes in inguinal WAT. Changes in insulin signaling, circulating natriuretic peptides and adipokines, and varied expression of adipose genes associated with altered insulin response/glucose handling and thermogenesis occurred prior to any functional decline in transverse aortic constriction hearts. The findings demonstrate multiphasic responses in extracardiac metabolism to pathogenic cardiac stress, with early iWAT browning providing potential metabolic benefits.
