Ultrasound‐Induced Nitric Oxide‐Propelled Nanomotor for Multimodal Theranostics of Cancer with Deep Penetration and Extended Lifetime

open access: yesAdvanced Science, EarlyView.
A hollow nanomotor (PM‐HMSN/Arg) propelled by ultrasound‐triggered nitric oxide (NO) was developed. The nanomotor employs a “tethering‐relaxing‐drilling” mechanism to overcome biological barriers, enabling multimodal theranostics of cancer with deep penetration and extended lifetime.

MASP-2 Is a Heparin-Binding Protease; Identification of Blocking Oligosaccharides

open access: yesFrontiers in Immunology, 2020
It is well-known that heparin and other glycosaminoglycans (GAGs) inhibit complement activation. It is however not known whether fractionation and/or modification of GAGs might deliver pathway-specific inhibition of the complement system.

The lectin pathway of complement activation

open access: yes, 2007
The complement system is an important immune system mechanism involved in both the recognition and elimination of invading pathogens. It is activated by three different pathways: The classical pathway, which relies on binding of C1, and results in the cleavage of C4 and C2 through activation of C1r and C1s; the alternative pathway that relies on the ...

Properdin and factor H: Opposing players on the alternative complement pathway "see-saw" [PDF]

open access: yes, 2013
This article has been made available through the Brunel Open Access Publishing Fund.Properdin and factor H are two key regulatory proteins having opposite functions in the alternative complement pathway.

Semaphorin 3E‐Plexin‐D1 Pathway Downstream of the Luteinizing Hormone Surge Regulates Ovulation, Granulosa Cell Luteinization, and Ovarian Angiogenesis in Mice

open access: yesAdvanced Science, EarlyView.
The Semaphorin 3E (Sema3E)‐Plexin‐D1 pathway mediated by C/EBPα and C/EBPβ downstream of the luteinizing hormone (LH) surge plays important roles in the mouse preovulatory ovary. Timely activation and suppression of this pathway during the preovulatory stage are crucial for ovulation, corpus luteum formation, and proper angiogenesis.

Targeting Human Dendritic Cells with Lewis X Modified Liposomes [PDF]

open access: yes, 2010
In this short report, we demonstrate that liposomes bearing the Lewis X trisaccharide on the surface (“Awesosomes”) efficiently target human dendritic cells.

Wireless In Situ Catalytic Electron Signaling‐Mediated Transcriptomic Reprogramming for Neuron Regeneration via Adaptable Antennas

open access: yesAdvanced Science, EarlyView.
A wireless‐charging sustained oxygen release from conductive microgels (SOCO) served as an antenna and an on‐demand O2 release for nerve regeneration is developed. Introducing “electromagnetic messenger”, using external alternating magnetic field (AMF) to enhance catalytic oxygen release and electrical stimulation to promote the reconstruction of blood

Complement classical and alternative pathway activation contributes to diabetic kidney disease progression: a glomerular proteomics on kidney biopsies

open access: yesScientific Reports
Increasing evidence points toward an essential role for complement activation in the pathogenesis of diabetic kidney disease (DKD). However, the precise molecular mechanisms remain unclear, and the pathway predominantly contributing to complement ...

High-Resolution, Three-Dimensional Reconstruction of the Outflow Tract Demonstrates Segmental Differences in Cleared Eyes [PDF]

open access: yesarXiv, 2017
Purpose: The rate of conventional aqueous humor outflow is the highest nasally. We hypothesized that this is reflected in regionally different outflow structures and analyzed the entire limbus by high-resolution, full-thickness ribbon-scanning confocal microscopy (RSCM).
