レジオネラは土壌細菌で世界中に分布しているが,近代の文化的生活における人工環境の至る所で増殖し,近年新たな展開を見せている.特に,人工環境水においては共存するアメーバを媒体として大量に増殖し,ありとあらゆる環境水からレジオネラ感染の危険性が高まっている.人工環境水の消毒の問題は人体への影響を考慮する必要があり,困難をきわめている状態である.わが国にはビル管理基準としての冷却塔におけるレジオネラ症防止指針が作成されているが,米国のCDCのような院内感染防止指針やその他の環境水に対する水の管理基準の策定はこれからである.診断法はPCR法や尿中抗原検出などかなりの進歩が見られているので,疑わしい症例では積極的にしかるべき施設へ依頼してでも確定診断を得る努力をする必要がある.

An isoform of 14‐3‐3 protein regulates transbilayer lipid movement at the plasma membrane
Loss of 14‐3‐3ζ in CHO cells confers resistance to exogenous phosphatidylserine (PS) and impairs endocytosis‐independent inward flip‐flop of fluorescent PS at the plasma membrane. RNAi‐mediated knockdown reproduces this defect, while no additive effect is seen in ATP11C‐deficient cells.

The ubiquitin ligase RNF115 is required for the clearance of damaged lysosomes
Upon lysosomal rupture, an E3 ubiquitin ligase RNF115 translocates from the cytosol to the damaged lysosomal membrane. Moreover, RNF115 depletion impairs the clearance of damaged lysosomes, identifying it as a key regulator of lysosomal quality control.

Infectious diseases is a broad discipline that is almost unique in contemporary medicine with its ability to cure and prevent disease, to identify specific disease causes (microbes), and to deal with diverse, sometimes massive outbreaks. The value of the infectious disease practitioner is now magnified by the crisis of antibiotic resistance, the ...

pH‐mediated activation of the lysosomal arginine sensor SLC38A9
Cells monitor nutrient levels via the lysosomal transporter SLC38A9 to activate the mechanistic target of rapamycin complex 1 (mTORC1). This study reveals that SLC38A9 function is regulated by pH. We identified histidine 544 as a critical pH sensor that undergoes conformational changes to control amino acid efflux from lysosomes; therefore, it ...

Development of therapies targeting cancer‐associated fibroblasts (CAFs) necessitates preclinical model systems that faithfully represent CAF–tumor biology. We established an in vitro coculture system of patient‐derived pancreatic CAFs and tumor cell lines and demonstrated its recapitulation of primary CAF–tumor biology with single‐cell transcriptomics ...

The economic control of infectious diseases [PDF]
Despite interesting work on infectious diseases by such economists as Peter Francis, Michael Kremer, and Tomas Philipson, the literature does not set out the general structure of externalities involved in the prevention, and care of such diseases.

We show that the majority of the 18 analyzed recurrent cancer‐associated ERBB4 mutations are transforming. The most potent mutations are activating, co‐operate with other ERBB receptors, and are sensitive to pan‐ERBB inhibitors. Activating ERBB4 mutations also promote therapy resistance in EGFR‐mutant lung cancer.

Etoposide induces DNA damage, activating p53‐dependent apoptosis via caspase‐3/7, which cleaves PARP1. Dammarenediol II enhances this apoptotic pathway by suppressing O‐GlcNAc transferase activity, further decreasing O‐GlcNAcylation. The reduction in O‐GlcNAc levels boosts p53‐driven apoptosis and influences the Akt/GSK3β/mTOR signaling pathway ...
