Nephrotic Syndrome I : Introduction

27
Nephrotic Syndrome is a chronic kidney disorder defined by clinical findings such as severe proteinuria, hypoalbuminemia, hyperlipidemia, and edema. These symptoms result from damage to the glomeruli, the kidney’s filtering units, increasing their permeability to proteins.Definition and Meaning:Proteinuria, defined as the loss of more than 3.5 grams of protein per day in adults, is a crucial feature of nephrotic syndrome. This condition is often accompanied by edema, the accumulation of...

T Cell Types and Functions01:24

T Cell Types and Functions

1.4K
When T cells with CD4 markers are activated, they give rise to two types of effector cells: helper T cells and regulatory T cells. Meanwhile, T cells with CD8 markers differentiate into effector cytotoxic T cells. The differentiation of CD4 T cells into helper T cell subsets, such as Th1, Th2, and Th17 cells, is dependent on the antigen type, antigen-presenting cell, and regulatory cytokines.
Th1 cells stimulate dendritic cells to express necessary co-stimulatory molecules on their surfaces for...

Acute Kidney Injury II: Pathophysiology

72
Acute kidney injury (AKI) causes are categorized into three primary categories based on the location of the injury: prerenal, intrarenal (or intrinsic), and postrenal causes. This classification guides clinical management and illustrates how different pathways can impair kidney function.Etiology and Pathophysiology of Acute Kidney Injury1. Prerenal causesEtiology: Prerenal Acute Kidney Injury, the most common type, occurs when reduced blood flow to the kidneys decreases filtration capacity...

Type IV Collagen of Basal Lamina01:05

Type IV Collagen of Basal Lamina

2.4K
Type IV collagen is a 400 nm long, network-forming collagen that acts as a barrier between the epithelial and endothelial cells. Type IV collagen  forms the backbone of the basement membrane by scaffolding with laminin, entactin, proteoglycans, and fibronectin. Apart from rendering structural support to the basement membrane, it also helps entail signaling potentials necessary for both pathological and physiological functions.
A type IV collagen molecule has six alpha chains which can...

Renal Corpuscle01:20

Renal Corpuscle

3.3K
The glomerulus and Bowman's capsule are two essential components of the nephron, which is the functional unit of the kidney. These microscopic structures play a critical role in the process of blood filtration to produce urine.
Glomerulus: Structure and Function
The glomerulus is a tiny, intricate network of capillaries located at the beginning of the nephron. It's enveloped by the Bowman's capsule and receives its blood supply from an afferent arteriole, which divides into numerous...

Intracellular Signaling Affects Focal Adhesions01:17

Intracellular Signaling Affects Focal Adhesions

2.8K
Integrins act both as extracellular input receivers and as intracellular processing activators. As their name suggests, integrins are entirely integrated into the membrane structure. Their hydrophobic membrane-spanning regions interact with the phospholipid bilayer's hydrophobic region. These membrane receptors provide extracellular attachment sites for effectors like hormones and growth factors. They activate intracellular response cascades when their effectors are bound and active.

  • 腎臓科
  • 分子生物学
  • 免疫学

背景:

  • 狼性腎炎 (LN) は,全身性狼症の一般的な合併症である.
  • 循環型RNA MTND5 (circMTND5) は,miR6812との相互作用によって,LNの病原化に関与している.
  • LNにおけるcircMTND5と相互作用するRNA結合タンパク質 (RBPs) の役割は不明である.

研究 の 目的:

  • LNの進行におけるcircMTND5とRBPsの相互作用を調査する.
  • LNの病原性における circMTND5の根本的なメカニズムを明らかにする.
  • circMTND5がLNにおける管間線維症に影響するかどうかを判断する.

主な方法:

  • LN患者およびマウスの腎臓サンプルにおけるタンパク質およびcircRNA発現を分析するために,免疫染色体,ウエスタンブロット,およびqPCRを用いた.
  • ヒトの腎臓細胞におけるcircMTND5のA1CFへの結合が確認されました.
