Tumor necrosis factor is a necroptosis-associated alarmin. [PDF]

open access: yesFront Immunol, 2022
Necroptosis is a form of regulated cell death that can occur downstream of several immune pathways. While previous studies have shown that dysregulated necroptosis can lead to strong inflammatory responses, little is known about the identity of the ...

Unfolded and intermediate states of PrP play a key role in the mechanism of action of an antiprion chaperone

open access: yesProceedings of the National Academy of Sciences of the United States of America, 2021
Significance Many diseases involve the propagation of misfolded proteins as in prion diseases. Compounds that can inhibit conversion into misfolded conformers exist, but their mechanism of action remains poorly understood. By observing the effects of the

PrP meets alpha‐synuclein: Molecular mechanisms and implications for disease

open access: yesJournal of Neurochemistry, 2023
The discovery of prions has challenged dogmas and has revolutionized our understanding of protein‐misfolding diseases. The concept of self‐propagation via protein conformational changes, originally discovered for the prion protein (PrP), also applies to ...

Rabbit PrP Is Partially Resistant to in vitro Aggregation Induced by Different Biological Cofactors

open access: yesFrontiers in Neuroscience, 2021
Prion diseases have been described in humans and other mammals, including sheep, goats, cattle, and deer. Since mice, hamsters, and cats are susceptible to prion infection, they are often used to study the mechanisms of prion infection and conversion ...

Design, Development, and Validation of a Self-Aligning Mechanism for High-Torque Powered Knee Exoskeletons

open access: yesIEEE Transactions on Medical Robotics and Bionics, 2020
Powered knee exoskeletons aim to assist individuals with lower limb impairments by providing power and torque at the joint level. However, if the anatomical and exoskeleton joints are not perfectly aligned, the exoskeleton assistance may result in ...

Potential therapeutic role of microvesicles derived from mesenchymal stem cells and platelet-rich plasma in murine burn wound healing: scar regulation and antioxidant mechanism.

open access: yesFolia Morphologica, 2022
BACKGROUND Microvesicles (MVs) derived from mesenchymal stem cells exhibited an emerging promising therapy in many animal model diseases. Post-burn scars represent one of the significant challenges in wound healing processes.

Inhibition of the different complement pathways has varying impacts on the serum bactericidal activity and opsonophagocytosis against Haemophilus influenzae type b [PDF]

open access: yes, 2022
Defense against Haemophilus influenzae type b (Hib) is dependent on antibodies and complement, which mediate both serum bactericidal activity (SBA) and opsonophagocytosis.

How human papillomavirus replication and immune evasion strategies take advantage of the host DNA damage repair machinery [PDF]

open access: yes, 2017
The DNA damage response (DDR) is a complex signalling network activated when DNA is altered by intrinsic or extrinsic agents. DDR plays important roles in genome stability and cell cycle regulation, as well as in tumour transformation.
