まとめ

多発性硬化症 (MS) と光学スペクトル障害 (NMOSD) の患者ではカルパイン- 1とカルパイン- 2の濃度が上昇し,HMGB1経路による神経炎症の役割を示唆しています.

科学分野:

神経免疫学
神経炎症
脱エリン化する病気

背景:

MSやNMOSDのような脱ミエリン性疾患では信号伝達経路を理解することが重要です
HMGB1/TLR4/NF-κB経路は神経炎症に関与しています.

研究の目的:

カルパイン-1 (CAPN1) とカルパイン-2 (CAPN2) と HMGB1/TLR4/NF-κB経路の関係を調査する.
多発性硬化症 (pwMS) と光学スペクトル障害 (pwNMOSD) の患者でこれらのマーカーを比較する.

主な方法:

ELISAは,CAPN1,CAPN2,HMGB1,溶性TLR4 (sTLR4) とNF-κBのレベルを測定するために使用されました.
研究には36人のpwMS,9人のpwNMOSD,28人の対照群 (pwPTC) が含まれていた.

主要な成果:

pwNMSは,pwNMOSDと対照群と比較して,CAPN1とCAPN2のレベルが著しく高かった.
HMGB1,sTLR4,またはNF- kBのレベルでは,グループ間で有意な差異は見られなかった.
pwMSにおけるCAPN1とCAPN2と, pwMSにおけるCAPN1とHMGB1との間に正の相関が認められた.

結論:

CAPN1は,HMGB1シグナル伝達を通じて,MSにおける神経炎症に寄与する可能性があります.
より大きなコホートと縦断研究によるさらなる研究が必要である.
CAPN1阻害を研究することで,MSの治療に関する洞察が得られます.

NF-κB-dependent Signaling Pathway

7.8K

The transcription factor NF-κB was discovered in 1986 in the lab of Nobel laureate Professor David Baltimore, for its interaction with the immunoglobulin light chain enhancer in B-cells. After more than three decades of study, it is now evident that NF-κB regulates the expression of over 100 genes. Most of these genes play an essential role in the innate and adaptive immune responses as well as the inflammatory responses of animals.

Calmodulin-dependent Signaling

5.3K

Calmodulin (CaM) is a calcium-binding protein in eukaryotes that controls various calcium-regulated cellular processes. It has four calcium-binding sites that bind calcium to form the calcium-calmodulin ( Ca2+-CaM) complex. GPCR stimulation increases the calcium levels in the cells that bind to CaM and induces a conformational change.
The Ca2+-CaM complex does not have enzymatic activity by itself. Instead, the complex binds downstream target proteins, including membrane proteins or enzymes,...

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...

The JAK-STAT Signaling Pathway

9.2K

Several cytokine receptors have tightly bound Janus kinase or JAK proteins attached at their cytosolic tail. Small signaling molecules such as cytokines, growth hormones, or prolactins bind to the cytokine receptors and initiate their dimerization. The dimerization brings the cytosolic JAKs together that trans-phosphorylate and activates each other. The activated JAKs now phosphorylate cytosolic tails of the cytokine receptors, which serve as binding sites for adaptor proteins such as SH2...

MAPK Signaling Cascades

6.0K

Mitogen-activated protein kinase, or MAPK pathway, activates three sequential kinases to regulate cellular responses such as proliferation, differentiation, survival, and apoptosis. The canonical MAPK pathway starts with a mitogen or growth factor binding to an RTK. The activated RTKs stimulate Ras, which recruits Raf or MAP3 Kinase (MAPKKK), the first kinase of the MAPK signaling cascade. Raf further phosphorylates and activates MEK or MAP2 Kinases (MAPKK), which in turn phosphorylates MAP...

Interactions Between Signaling Pathways

6.4K

Signaling cascades usually lack linearity. Multiple pathways interact and regulate one another, allowing cells to integrate and respond to diverse environmental stimuli.
Convergence and divergence, and cross-talk between signaling pathways
Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...
