Recurrent Cholera Outbreaks, Democratic Republic of the Congo, 2008-2017.

Emerg Infect Dis 2019 May;25(5):856-864

In 2017, the exacerbation of an ongoing countrywide cholera outbreak in the Democratic Republic of the Congo resulted in >53,000 reported cases and 1,145 deaths. To guide control measures, we analyzed the characteristics of cholera epidemiology in DRC on the basis of surveillance and cholera treatment center data for 2008-2017. The 2017 nationwide outbreak resulted from 3 distinct mechanisms: considerable increases in the number of cases in cholera-endemic areas, so-called hot spots, around the Great Lakes in eastern DRC; recurrent outbreaks progressing downstream along the Congo River; and spread along Congo River branches to areas that had been cholera-free for more than a decade.

The incidence, aetiology, and adverse clinical consequences of less severe diarrhoeal episodes among infants and children residing in low-income and middle-income countries: a 12-month case-control study as a follow-on to the Global Enteric Multicenter Study (GEMS).

Lancet Glob Health 2019 May;7(5):e568-e584

University of Maryland School of Medicine, Baltimore, MD, USA.

Background: Diarrheal diseases remain a leading cause of illness and death among children younger than 5 years in low-income and middle-income countries. The Global Enteric Multicenter Study (GEMS) has described the incidence, aetiology, and sequelae of medically attended moderate-to-severe diarrhoea (MSD) among children aged 0-59 months residing in censused populations in sub-Saharan Africa and south Asia, where most child deaths occur. To further characterise this disease burden and guide interventions, we extended this study to include children with episodes of less-severe diarrhoea (LSD) seeking care at health centres serving six GEMS sites.

Chloroethylating anticancer drug-induced mutagenesis and its repair in .

Genes Environ 2019 5;41:11. Epub 2019 Apr 5.

1Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University, Tsushima-naka, Kita-ku, Okayama, 700-8530 Japan.

Background: Chloroethylnitrosourea (CENU) derivatives, such as nimustine (ACNU) and carmustine (BCNU), are employed in brain tumor chemotherapy due to their ability to cross the blood-brain barrier. They are thought to suppress tumor development through DNA chloroethylation, followed by the formation of interstrand cross-links (ICLs) that efficiently block replication and transcription. However, the alkylation of DNA and ICLs may trigger genotoxicity, leading to tumor formation as a side effect of the chemotherapeutic treatment. Read More

Unmasking herd protection by an oral cholera vaccine in a cluster-randomized trial.

Int J Epidemiol 2019 Apr 9. Epub 2019 Apr 9.

Infectious Diseases Division, International Centre for Diarrhoeal Disease Research, Bangladesh, Dhaka, Bangladesh.

Background: Several studies have shown that inactivated, whole-cell oral cholera vaccines (OCVs) confer both direct protection on vaccinees and herd protection on populations. Because our earlier cluster-randomized effectiveness trial (CRT) in urban Bangladesh failed to detect OCV herd protection, we reanalysed the trial to assess whether herd effects were masked in our original analysis.

Methods: A total of 267 270 persons were randomized to 90 approximately equal-sized clusters. Read More

Department of Endocrinology and Metabolism & Laboratory of Endocrinology, Department of Clinical Chemistry, Amsterdam Neuroscience, Amsterdam UMC, University of Amsterdam, Amsterdam, The Netherlands.

The hypothalamic neuropeptide Y (NPY) circuitry is a key regulator of feeding behavior. NPY also acts in the mesolimbic dopaminergic circuitry, where it can increase motivational aspects of feeding behavior through effects on dopamine output in the nucleus accumbens (NAc) and on neurotransmission in the ventral tegmental area (VTA). Endogenous NPY in the NAc originates from local interneurons and afferent projections from the hypothalamic arcuate nucleus (Arc). Read More

Louis Pasteur invited his main collaborators, who had accompanied him during his previous investigations at École Normale Supérieure, to join him in his new institute. They contributed to the principle discoveries of Pasteur, such as the fight against spontaneous generation, the identification of the ferments of putrefaction, the fight against the silk worm disease, the research on wine and beer, and the set-up of the first vaccines against avian cholera, anthrax, swine erysipelas, and rabies.

Bacterial AB toxins inhibit the growth of gut bacteria by targeting ganglioside-like glycoconjugates.

Nat Commun 2019 03 27;10(1):1390. Epub 2019 Mar 27.

Department of Microbiology and Complex Carbohydrate Research Center, University of Georgia, Athens, GA, 30602, USA.

The AB toxins cholera toxin (CT) from Vibrio cholerae and heat-labile enterotoxin (LT) from enterotoxigenic Escherichia coli are notorious for their roles in diarrheal disease, but their effect on other intestinal bacteria remains unexplored. Another foodborne pathogen, Campylobacter jejuni, can mimic the GM1 ganglioside receptor of CT and LT. Here we demonstrate that the toxin B-subunits (CTB and LTB) inhibit C. Read More

Neuromuscular Plasticity in a Mouse Neurotoxic Model of Spinal Motoneuronal Loss.

Int J Mol Sci 2019 Mar 26;20(6). Epub 2019 Mar 26.

Laboratory of Cellular and Molecular Physiology, Department of Biomedical and Biotechnological Sciences, Section of Physiology, University of Catania, Catania 95123, Italy.

Despite the relevant research efforts, the causes of amyotrophic lateral sclerosis (ALS) are still unknown and no effective cure is available. Many authors suggest that ALS is a multi-system disease caused by a network failure instead of a cell-autonomous pathology restricted to motoneurons. Although motoneuronal loss is the critical hallmark of ALS given their specific vulnerability, other cell populations, including muscle and glial cells, are involved in disease onset and progression, but unraveling their specific role and crosstalk requires further investigation.

LPS enhances CTB-INSULIN induction of IDO1 and IL-10 synthesis in human dendritic cells.

Cell Immunol 2019 Apr 19;338:32-42. Epub 2019 Mar 19.

Division of Biochemistry, Center for Health Disparity and Molecular Medicine, Loma Linda University, School of Medicine, Loma Linda, CA 92354, United States. Electronic address:

Autoantigen-specific immunotherapy promises effective treatment for devastating tissue specific autoimmune diseases like multiple sclerosis (MS) and type 1 diabetes (T1D). Because activated dendritic cells (DCs) stimulate the differentiation of autoreactive T cells involved in the initiation of autoimmunity, blocking the activation of DCs may be an effective strategy for inhibiting tissue specific autoimmunity. Following this approach, immature DCs were shown to remain inactive after treatment with chimeric fusion proteins composed of the cholera toxin B subunit adjuvant linked to autoantigens like proinsulin (CTB-INS).

Competition between mobile genetic elements drives optimization of a phage-encoded CRISPR-Cas system: insights from a natural arms race.

Philos Trans R Soc Lond B Biol Sci 2019 May;374(1772):20180089

1 Department of Plant and Microbial Biology, University of California , 111 Koshland Hall, Berkeley, CA 94720 , USA.

CRISPR-Cas systems function as adaptive immune systems by acquiring nucleotide sequences called spacers that mediate sequence-specific defence against competitors. Uniquely, the phage ICP1 encodes a Type I-F CRISPR-Cas system that is deployed to target and overcome PLE, a mobile genetic element with anti-phage activity in Vibrio cholerae. Here, we exploit the arms race between ICP1 and PLE to examine spacer acquisition and interference under laboratory conditions to reconcile findings from wild populations. Read More

Convenient methodology for extraction and subsequent selective propagation of mouse melanocytes in culture from adult mouse skin tissue.

Biochem Biophys Rep 2019 Jul 22;18:100619. Epub 2019 Feb 22.

Department of Cell Biology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama, Japan.

Mouse melanoma B16-BL6 cells are useful cells for cancer metastatic studies. To understand the metastatic principle at molecular levels, it is necessary to carry out experiments in which cancer cells and their normal counterparts are compared. However, unlike normal human melanocytes, preparation of normal mouse melanocytes is quite difficult due to the lack of marketing and insufficient information on an established protocol for primary culture of mouse melanocytes.

Neuron-targeted caveolin-1 improves neuromuscular function and extends survival in SOD1 mice.

FASEB J 2019 Mar 20:fj201802652RR. Epub 2019 Mar 20.

Veterans Affairs San Diego Healthcare System, San Diego, California, USA.

Interventions that preserve motor neurons or restore functional motor neuroplasticity may extend longevity in amyotrophic lateral sclerosis (ALS). Delivery of neurotrophins may potentially revive degenerating motor neurons, yet this approach is dependent on the proper subcellular localization of neurotrophin receptor (NTR) to plasmalemmal signaling microdomains, termed membrane/lipid rafts (MLRs). We previously showed that overexpression of synapsin-driven caveolin-1 (Cav-1) ( SynCav1) increases MLR localization of NTR [ e. Read More
