25 Jul 2019TL;DR: In this paper, methods for treating and identifying a subject having a steroid resistant disease or condition were described, and methods for identifying and treating such a subject were described. But none of these methods were discussed in detail.
Abstract: Disclosed herein are methods treating and identifying a subject having a steroid resistant disease or condition.

TL;DR: It is found that memory CD4 T cells generated by infection or immunisation survive secondary activation with antigen delivered without adjuvant, regardless of their location in secondary lymphoid organs or peripheral tissues, and data suggest that tolerance induction in memory T cells is partial and can be reversed.
Abstract: Memory T cells respond rapidly in part because they are less reliant on heightened levels of costimulatory molecules. This presents challenges to silencing memory T cells in tolerance strategies for autoimmunity or allergy. We find that memory CD4 T cells generated by infection or immunisation survive secondary activation with antigen delivered without adjuvant, regardless of their location in secondary lymphoid organs or peripheral tissues. These cells were, however, functionally altered following a tertiary immunisation with antigen and adjuvant, proliferating poorly but maintaining their ability to produce inflammatory cytokines. Transcriptional and cell cycle analysis of these memory CD4 T cells suggest they are unable to commit fully to cell division potentially because of low expression of DNA repair enzymes. In contrast, these memory CD4 T cells could proliferate following tertiary reactivation by viral re-infection. These data suggest that tolerance induction in memory CD4 T cells is partial and can be reversed.

TL;DR: A data processing paradigm to identify key factors in biological processes via systematic collection of gene expression datasets, primary analysis of data, and evaluation of consistent signals is introduced and can lead to fruitful results for studying molecular mechanisms in an era of explosive accumulation of publicly available biological data.
Abstract: A large volume of biological data is being generated for studying mechanisms of various biological processes. These precious data enable large-scale computational analyses to gain biological insights. However, it remains a challenge to mine the data efficiently for knowledge discovery. The heterogeneity of these data makes it difficult to consistently integrate them, slowing down the process of biological discovery. We introduce a data processing paradigm to identify key factors in biological processes via systematic collection of gene expression datasets, primary analysis of data, and evaluation of consistent signals. To demonstrate its effectiveness, our paradigm was applied to epidermal development and identified many genes that play a potential role in this process. Besides the known epidermal development genes, a substantial proportion of the identified genes are still not supported by gain- or loss-of-function studies, yielding many novel genes for future studies. Among them, we selected a top gene for loss-of-function experimental validation and confirmed its function in epidermal differentiation, proving the ability of this paradigm to identify new factors in biological processes. In addition, this paradigm revealed many key genes in cold-induced thermogenesis using data from cold-challenged tissues, demonstrating its generalizability. This paradigm can lead to fruitful results for studying molecular mechanisms in an era of explosive accumulation of publicly available biological data.

01 Jan 2017TL;DR: Genotypic methods are increasingly employed as screening tests and complement conventional antimicrobial susceptibility testing, and accurate detection of clinically meaningful minimal inhibitory concentrations is the prerequisite for pharmacokinetic and pharmacodynamic correlations.
Abstract: Timely detection of patients harboring drug-resistant Mycobacterium tuberculosis strains is of paramount importance for effective treatment and also for preventing epidemics of drug-resistant tuberculosis. Bacteriologic methods currently in use for detection of drug resistance are the agar proportion method and the use of automated liquid medium systems. In addition, genotypic methods are increasingly employed as screening tests and complement conventional antimicrobial susceptibility testing. Accurate detection of clinically meaningful minimal inhibitory concentrations is the prerequisite for pharmacokinetic and pharmacodynamic correlations.
