A comprehensive analysis of the immune system in healthy Vietnamese people.

Lifestyle, diet, socioeconomic status and genetics all contribute to heterogeneity in immune responses. Vietnam is plagued with a variety of health problems, but there are no available data on immune system values in the Vietnamese population. This study aimed to establish reference intervals for immune cell parameters specific to the healthy Vietnamese population by utilizing multi-color flow cytometry (MCFC).

Clinical impact of the two ART resistance markers, K13 gene mutations and DPC3 in Vietnam.

Background: In Vietnam, a rapid decline of P. falciparum malaria cases has been documented in the past years, the number of Plasmodium falciparum malaria cases has rapidly decreased passing from 19.638 in 2012 to 4.

Evaluation of a real-time PCR assay for malaria diagnosis in patients from Vietnam and in returned travellers.

Real-time PCR diagnosis of malaria has advantages over traditional microscopic methods, especially when parasitaemia is low and when dealing with mixed infections. We have developed a new real-time PCR with specific genes in each Plasmodium species present only in one copy to identify the four pathogenic Plasmodium spp. for humans.

Bph1p, the Saccharomyces cerevisiae homologue of CHS1/beige, functions in cell wall formation and protein sorting.

Mutations in the Chediak-Higashi syndrome gene (CHS1) and its murine homologue Beige result in the formation of enlarged lysosomes. BPH1 (Beige Protein Homologue 1) encodes the Saccharomyces cerevisiae homologue of CHS1/Beige. BPH1 is not essential and the encoded protein was found to be both cytosolic and peripherally bound to a membrane.

Characterization of Vta1p, a class E Vps protein in Saccharomyces cerevisiae.

We identified VTA1 in a screen for mutations that result in altered vacuole morphology. Deletion of VTA1 resulted in delayed trafficking of the lipophilic dye FM4-64 to the vacuole and altered vacuolar morphology when cells were exposed to the dye 5-(and 6)-carboxy-2',7'-dichlorofluorescein diacetate (CDCFDA). Deletion of class E vacuolar protein sorting (VPS) genes, which encode proteins that affect multivesicular body formation, also showed altered vacuolar morphology upon exposure to high concentrations of CDCFDA.

Use of expression constructs to dissect the functional domains of the CHS/beige protein: identification of multiple phenotypes.

The Chediak-Higashi Syndrome (CHS) and the orthologous murine disorder beige are characterized at the cellular level by the presence of giant lysosomes. The CHS1/Beige protein is a 3787 amino acid protein of unknown function. To determine functional domains of the CHS1/Beige protein, we generated truncated constructs of the gene/protein.
