Anthrax lethal toxin induced lysosomal membrane permeabilization and cytosolic cathepsin release is Nlrp1b/Nalp1b-dependent.

NOD-like receptors (NLRs) are a group of cytoplasmic molecules that recognize microbial invasion or 'danger signals'. Activation of NLRs can induce rapid caspase-1 dependent cell death termed pyroptosis, or a caspase-1 independent cell death termed pyronecrosis. Bacillus anthracis lethal toxin (LT), is recognized by a subset of alleles of the NLR protein Nlrp1b, resulting in pyroptotic cell death of macrophages and dendritic cells. Here we show that LT induces lysosomal membrane permeabilization (LMP). The presentation of LMP requires expression of an LT-responsive allele of Nlrp1b, and is blocked by proteasome inhibitors and heat shock, both of which prevent LT-mediated pyroptosis. Further the lysosomal protease cathepsin B is released into the cell cytosol and cathepsin inhibitors block LT-mediated cell death. These data reveal a role for lysosomal membrane permeabilization in the cellular response to bacterial pathogens and demonstrate a shared requirement for cytosolic relocalization of cathepsins in pyroptosis and pyronecrosis

The need for accredited training in gynaecological oncology: a report from the European Network of Young Gynaecological Oncologists (ENYGO).

BACKGROUND: Primary data on training experiences of European gynaecological oncology trainees are lacking. This study aims to evaluate trainee profile, satisfaction and factors affecting the training experience in gynaecological oncology in Europe. PATIENTS AND METHODS: A web-based anonymous survey sent to ENYGO members/trainees in July 2011. It included sociodemographic information and a 22-item (1-5 Likert scale) questionnaire evaluating training experience in gynaecological oncology. Chi-square tests were used for evaluating the independence of categorical variables and t-test (parametric)/Mann-Whitney (non-parametric) tests for differences between two independent groups on continuous data. Cluster analysis was used to identify groupings in multivariate data and Cronbach's-alpha for questionnaire reliability. A multivariable linear regression model was used to assess the effect of variables on training satisfaction. RESULTS: One hundred and nineteen gynaecological-oncology trainees from 31 countries responded. The mean age was 37.4 (S.D, 5.3) years and 55.5% were in accredited training posts. Two clusters identified in the cohort (Calinski-Harabasz, CH = 47.35) differed mainly by accredited training (P = 0.003). The training-satisfaction score (TSS) had high reliability (Cronbach's alpha, 0.951) and was significantly associated with accredited posts (P < 0.0005), years of training (P = 0.001) and salary (P = 0.002). The TSS was independent of age (P = 0.360), working hours (P = 0.620), overtime-pay (P = 0.318), annual leave (P = 0.933), gender (P = 0.545) and marital status (P = 0.731). Accredited programme trainees scored significantly higher than others in 17 of 22 aspects of training. The areas of greater need included advanced laparoscopic/urological/colorectal surgery, radiation oncology, palliative-care, cancer genetics and research opportunities. CONCLUSIONS: Our data demonstrate the importance of accredited training and the need for harmonisation of gynaecological oncology training within Europe

Amoeba predation of <i>Cryptococcus</i>:A quantitative and population genomic evaluation of the accidental pathogen hypothesis

The “Amoeboid Predator-Fungal Animal Virulence Hypothesis” posits that interactions with environmental phagocytes shape the evolution of virulence traits in fungal pathogens. In this hypothesis, selection to avoid predation by amoeba inadvertently selects for traits that contribute to fungal escape from phagocytic immune cells. Here, we investigate this hypothesis in the human fungal pathogens Cryptococcus neoformans and Cryptococcus deneoformans. Applying quantitative trait locus (QTL) mapping and comparative genomics, we discovered a cross-species QTL region that is responsible for variation in resistance to amoeba predation. In C. neoformans, this same QTL was found to have pleiotropic effects on melanization, an established virulence factor. Through fine mapping and population genomic comparisons, we identified the gene encoding the transcription factor Bzp4 that underlies this pleiotropic QTL and we show that decreased expression of this gene reduces melanization and increases susceptibility to amoeba predation. Despite the joint effects of BZP4 on amoeba resistance and melanin production, we find no relationship between BZP4 genotype and escape from macrophages or virulence in murine models of disease. Our findings provide new perspectives on how microbial ecology shapes the genetic architecture of fungal virulence, and suggests the need for more nuanced models for the evolution of pathogenesis that account for the complexities of both microbe-microbe and microbe-host interactions

The gynecologic oncologist in academic departments : Report of survey

Now that the subspecialty of gynecologic oncology is well established within the specialty of obstetrics and gynecology, it seems timely to evaluate the pros and cons, the strengths and weaknesses of such a program as it interrelates with other programs in an academic department. A survey is presented which reflects the beliefs of both members and candidate members of the Society of Gynecologic Oncologists on such issues as gynecologic oncologists as chairmen of departments; teaching demands; time commitments to patient care and research in an academic institution; and surgical privileges for gastro-intestinal and urologic procedures in various hospitals. Financial and budgetary items are also discussed. Perspectives from three different points of view are presented as a discussion of the report of the survey.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/24676/1/0000095.pd

Unisexual and Heterosexual Meiotic Reproduction Generate Aneuploidy and Phenotypic Diversity De Novo in the Yeast Cryptococcus neoformans

Aneuploidy is known to be deleterious and underlies several common human diseases, including cancer and genetic disorders such as trisomy 21 in Down's syndrome. In contrast, aneuploidy can also be advantageous and in fungi confers antifungal drug resistance and enables rapid adaptive evolution. We report here that sexual reproduction generates phenotypic and genotypic diversity in the human pathogenic yeast Cryptococcus neoformans, which is globally distributed and commonly infects individuals with compromised immunity, such as HIV/AIDS patients, causing life-threatening meningoencephalitis. C. neoformans has a defined a-α opposite sexual cycle; however, >99% of isolates are of the α mating type. Interestingly, α cells can undergo α-α unisexual reproduction, even involving genotypically identical cells. A central question is: Why would cells mate with themselves given that sex is costly and typically serves to admix preexisting genetic diversity from genetically divergent parents? In this study, we demonstrate that α-α unisexual reproduction frequently generates phenotypic diversity, and the majority of these variant progeny are aneuploid. Aneuploidy is responsible for the observed phenotypic changes, as chromosome loss restoring euploidy results in a wild-type phenotype. Other genetic changes, including diploidization, chromosome length polymorphisms, SNPs, and indels, were also generated. Phenotypic/genotypic changes were not observed following asexual mitotic reproduction. Aneuploidy was also detected in progeny from a-α opposite-sex congenic mating; thus, both homothallic and heterothallic sexual reproduction can generate phenotypic diversity de novo. Our study suggests that the ability to undergo unisexual reproduction may be an evolutionary strategy for eukaryotic microbial pathogens, enabling de novo genotypic and phenotypic plasticity and facilitating rapid adaptation to novel environments

Coaching primary care clinics for HPV vaccination quality improvement: Comparing in-person and webinar implementation

State health departments commonly use quality improvement coaching as an implementation strategy for improving low human papillomavirus (HPV) vaccination coverage, but such coaching can be resource intensive. To explore opportunities for improving efficiency, we compared in-person and webinar delivery of coaching sessions on implementation outcomes, including reach, acceptability, and delivery cost. In 2015, we randomly assigned 148 high-volume primary care clinics in Illinois, Michigan, and Washington State to receive either in-person or webinar coaching. Coaching sessions lasted about 1 hr and used our Immunization Report Card to facilitate assessment and feedback. Clinics served over 213,000 patients ages 11–17. We used provider surveys and delivery cost assessment to collect implementation data. This report is focused exclusively on the implementation aspects of the intervention. More providers attended in-person than webinar coaching sessions (mean 9 vs. 5 providers per clinic, respectively, p = .004). More providers shared the Immunization Report Card at clinic staff meetings in the in-person than webinar arm (49% vs. 20%; p = .029). In both arms, providers’ belief that their clinics’ HPV vaccination coverage was too low increased, as did their self-efficacy to help their clinics improve (p < .05). Providers rated coaching sessions in the two arms equally highly on acceptability. Delivery cost per clinic was $733 for in-person coaching versus$461 for webinar coaching. In-person and webinar coaching were well received and yielded improvements in provider beliefs and self-efficacy regarding HPV vaccine quality improvement. In summary, in-person coaching cost more than webinar coaching per clinic reached, but reached more providers. Further implementation research is needed to understand how and for whom webinar coaching may be appropriate

Dual action antifungal small molecule modulates multidrug efflux and TOR signaling.

There is an urgent need for new strategies to treat invasive fungal infections, which are a leading cause of human mortality. Here, we establish two activities of the natural product beauvericin, which potentiates the activity of the most widely deployed class of antifungal against the leading human fungal pathogens, blocks the emergence of drug resistance, and renders antifungal-resistant pathogens responsive to treatment in mammalian infection models. Harnessing genome sequencing of beauvericin-resistant mutants, affinity purification of a biotinylated beauvericin analog, and biochemical and genetic assays reveals that beauvericin blocks multidrug efflux and inhibits the global regulator TORC1 kinase, thereby activating the protein kinase CK2 and inhibiting the molecular chaperone Hsp90. Substitutions in the multidrug transporter Pdr5 that enable beauvericin efflux impair antifungal efflux, thereby impeding resistance to the drug combination. Thus, dual targeting of multidrug efflux and TOR signaling provides a powerful, broadly effective therapeutic strategy for treating fungal infectious disease that evades resistance

Proteolytic Processing of Nlrp1b Is Required for Inflammasome Activity

Nlrp1b is a NOD-like receptor that detects the catalytic activity of anthrax lethal toxin and subsequently co-oligomerizes into a pro-caspase-1 activation platform known as an inflammasome. Nlrp1b has two domains that promote oligomerization: a NACHT domain, which is a member of the AAA+ ATPase family, and a poorly characterized Function to Find Domain (FIIND). Here we demonstrate that proteolytic processing within the FIIND generates N-terminal and C-terminal cleavage products of Nlrp1b that remain associated in both the auto-inhibited state and in the activated state after cells have been treated with lethal toxin. Functional significance of cleavage was suggested by the finding that mutations that block processing of Nlrp1b also prevent the ability of Nlrp1b to activate pro-caspase-1. By using an uncleaved mutant of Nlrp1b, we established the importance of cleavage by inserting a heterologous TEV protease site into the FIIND and demonstrating that TEV protease processed this site and induced inflammasome activity. Proteolysis of Nlrp1b was shown to be required for the assembly of a functional inflammasome: a mutation within the FIIND that abolished cleavage had no effect on self-association of a FIIND-CARD fragment, but did reduce the recruitment of pro-caspase-1. Our work indicates that a post-translational modification enables Nlrp1b to function
