GATA4‐Driven Transcription of HtrA1 Promotes Cellular Senescence in Ménière's Disease and Age‐Related Audio‐Vestibular Dysfunction

Advanced Science, EarlyView.
This study identifies the HDAC6/GATA4/HtrA1 axis as a critical driver of cellular senescence in the inner ear. GATA4 nuclear translocation, facilitated by HDAC6 downregulation, transcriptionally activates HtrA1, promoting hair cell senescence, SASP, and audio‐vestibular dysfunction in models of Ménière's disease and age‐related audio‐vestibular ...

A Perspective on the Applications of Triphasic Gas Storage in Electrochemical Systems

Advanced Science, EarlyView.
Gas storage in microporous materials positioned locally at an electrode or electrocatalyst surface enhances electrochemical processes. Abstract Microporous materials store gases under dry conditions (e.g., hydrogen or oxygen via physisorption), but in some cases microporous materials also show triphasic (e.g., in a solid|gas|liquid system) gas storage ...

Paternal Circadian Disruption Impairs Offspring Cognition via Sperm microRNAs

Advanced Science, EarlyView.
Paternal circadian disruption remodels the sperm small RNA payload, elevating miR‐92a‐3p/miR‐25‐3p levels and perturbing early embryonic gene regulatory programs. Microinjection experiments and single‐embryo transcriptomics reveal sex‐specific developmental vulnerabilities, ultimately impairing offspring hippocampal synaptic plasticity and cognition ...

Targeting the PDK1/c‐Myc/SOX10 Signaling in Oligodendrocytes Alleviates Neuropathic Pain

Advanced Science, EarlyView.
This work reveals that oligodendrocyte homeostasis, mediated by PDK1, is a critical determinant of neuropathic pain (NPP) pathogenesis. Disruption of PDK1 in oligodendrocytes impairs SOX10‐dependent myelination programs through c‐Myc accumulation, leading to disrupted myelination and the pathophysiology of NPP.

The membrane attack complex

Seminars in Immunopathology, 1984
The “killer molecule” of complement is the membrane attack complex (MAC). It constitutes a supramolecular organization that is composed of approximately 20 protein molecules and has a molecular weight of about 1.7 million. The complex has five precursors, C5, C6, C7, C8, and C9, which are hydrophilic glycoproteins with molecular weights ranging from 70

Microvascular Deposition of Complement Membrane Attack Complex in Dermatomyositis

New England Journal of Medicine, 1986
We examined the role of the complement system in the pathogenesis of dermatomyositis. Using an antibody against the neoantigens of the terminal C5b-9 membrane attack complex, we performed immunocytochemical studies that localized this complex to the intramuscular microvasculature (arterioles and capillaries) of muscle biopsy specimens from 10 of 12 ...

Membrane permeability to macromolecules mediated by the membrane attack complex

Biochemistry, 1989
A simple and well-defined system of purified phospholipids and human complement proteins was used to study membrane permeability to macromolecules mediated by the membrane attack complex (MAC) of complement. Large unilamellar vesicles (LUVs) of phosphatidylcholine (PC) or phosphatidylserine (PS) containing trapped macromolecules [bovine pancreatic ...

The Membrane Attack Complex of Complement

Annual Review of Immunology, 1986
Cell-killing mechanisms are essential components of host defense against infectious agents, parasites, and malignant cells. We distinguish humoral and cellular killing mechanisms. Complement utilizes specific proteins to assemble its killer molecule. Macrophages generate active oxygen radicals that injure target membranes. Lymphocytes, like complement,

Structural Biology of the Membrane Attack Complex

2014
The complement system is an intricate network of serum proteins that mediates humoral innate immunity through an amplification cascade that ultimately leads to recruitment of inflammatory cells or opsonisation or killing of pathogens. One effector arm of this network is the terminal pathway of complement, which leads to the formation of the membrane ...
