概括

在大多数Jorge Lobo病 (JLd) 患者的巨细胞中发现了脂质滴 (LD),这表明它们可能会导致慢性真菌感染. 对JLd病原体中的LD进行进一步研究是有必要的.

科学领域:

菌类学菌类学是指菌类学.
免疫学免疫学免疫学
皮肤病学皮肤病学

背景情况:

霍尔赫·洛博病 (JLd) 是一种慢性真菌感染,由*Paracoccidioides lobogeorgii*引起.
组织病理学揭示了JLd病变中的M2极化巨细胞,与免疫逃避和感染持久性有关.
脂质滴 (LDs) 在JLd病原体中的作用仍然未被探索.

研究的目的:

调查霍尔赫·洛博病 (JLd) 皮肤病变中巨细胞内的脂质滴 (LD) 的存在和特征.
为了将LD与JLd中的M2巨细胞标志物相关联.

主要方法:

在54个JLd皮肤样本上进行了免疫组织化学检查.
抗阿迪波菲林抗体用于检测LD,而抗CD163和抗CD204抗体用于识别M2巨细胞.
半定量评估LD密度,并使用ImageJ.量化M2巨细胞密度.

主要成果:

在研究的JLd病例中,72.22%的巨细胞内发现了脂质滴 (LDs).
在53.85%的阳性病例中观察到高密度的LDs.
LDs的存在和密度独立于M2巨细胞密度.

结论:

宿主衍生的脂质滴 (LDs) 在Jorge Lobo疾病 (JLd) 期间经常存在于巨细胞中.
这些发现表明LDs在JLd的发病过程中可能发挥作用,可能有助于真菌的生存或调节宿主免疫反应.

Intralumenal Vesicles and Multivesicular Bodies

Intralumenal Vesicles and Multivesicular Bodies

Intraluminal vesicles (ILVs) are small vesicles 50-80 nm in diameter formed during the maturation of early endosomes. A specialized endosome containing numerous ILVs is called a multivesicular body (MVB). ILVs contain internalized molecules such as antigens, nucleic acids, proteins, and metabolites. Some of these molecules are released from the MVBs inside exosomes and are transported to other cells. Other MVBs contain molecules that are retained in the ILVs and are later degraded within the...

Liver Histology

Liver Histology

The microscopic anatomy of the liver is a complex and intricate system that comprises numerous structural units known as liver lobules, each of which is comparable in size to a sesame seed. These hexagonal structures consist of plates of liver cells or hepatocytes, which are characterized by their versatility and abundance of cellular apparatus like rough and smooth ER, Golgi apparatus, peroxisomes, and mitochondria.
Hepatocytes perform a variety of essential functions. They secrete...
