まとめ
好酸球増多症は移民に共通して見られる所見であり、糸状虫症や糞線虫症などの寄生虫感染症を示唆することが多い。診断努力にもかかわらず、多くの症例は未診断のままであり、輸入疾患に対する検査の改善が必要であることを強調している。
科学分野:
- 熱帯医学;感染症;寄生虫学
背景:
- 好酸球増多症は、熱帯/亜熱帯地域からの個人における寄生虫感染症の主要なバイオマーカーとして機能します。;輸入性好酸球増多症は、非風土病地域において診断上の課題をもたらします。
研究 の 目的:
- 輸入性好酸球増多症の頻度と原因を特定すること。;熱帯医学ユニットにおける移民患者の診断結果を分析すること。
主な方法:
- 773人の移民患者(2008-2023年)の後ろ向き分析。;好酸球増多症の有病率、感染性対非感染性の原因の評価。;特定の寄生虫病因および重複感染の特定。
主要な成果:
- 患者の43.7%で好酸球増多症が検出され、4.4%は非感染性の原因でした。;糸状虫症(12.1%)、糞線虫症(9.9%)、住血吸虫症(4.6%)を筆頭に、特定の寄生虫診断が49.2%で到達しました。;アフリカからの患者は診断の可能性が高いことを示しました。;58人の患者が重複感染していました。
結論:
- 好酸球増多症は移民に蔓延しており、線虫症の重要な指標です。;評価にもかかわらず、好酸球増多症の症例のほぼ半数が未診断のままであり、より良い診断ツールが必要とされています。;糸状虫症、糞線虫症、住血吸虫症が主な原因です。輸入寄生虫感染症の管理には、強化された診断が不可欠です。

Protein Import into the Peroxisomes
5.4K
Cells contain membrane-bound organelles called peroxisomes that oxidize organic molecules by transferring hydrogen atoms to oxygen, producing hydrogen peroxide. Peroxisomes enzymatically convert the released hydrogen peroxide into water and oxygen.
Peroxisomal Protein Import:
Peroxisomes lack the genetic machinery required to code for their own proteins. Hence, most peroxisomal membrane, lumenal and transmembrane proteins are synthesized in the cytoplasm or ER and transported to the peroxisome...

ABC Transporters: Importer
3.5K
ATP-binding cassette or ABC transporters are a class of ATP-driven pumps that hydrolyze ATP to move solutes across the membrane. They can be grouped into importers and exporters. While exporters are present in all domains of life, importers exist only in bacteria and some plants.
In bacteria, based on the number of transmembrane helices and the chemical nature of their substrates, the ABC importers can be divided into three types:

Nuclear Localization Signals and Import
7.7K
Proteins targeted to the nucleus carry short stretches of amino acid sequences called the nuclear localization signal or NLS. Classical nuclear localization signals are of two types: monopartite and bipartite NLS. Monopartite classical NLS (cNLS) consists of a single cluster of 4-8 amino acids. Bipartite cNLS consists of two clusters of 2-3 amino acids and a 9-12 residue long proline-rich linker bridging the two clusters. Signal clusters are rich in positively charged amino acids such as...

Polygenic Traits
69.0K
When more than one gene is responsible for a given phenotype, the trait is considered polygenic. Human height is a polygenic trait. Studies have uncovered hundreds of loci that influence height, and there are believed to be many more. Due to the high number of genes involved, as well as environmental and nutritional factors, height varies significantly within a given population. The distribution of height forms a bell-shaped curve, with relatively few individuals in the population at the...
