Prion pathogenesis and secondary lymphoid organs (SLO): Tracking the SLO spread of prions to the brain [PDF]

, 2012
Prion diseases are subacute neurodegenerative diseases that affect humans and a range of domestic and free-ranging animal species. These diseases are characterized by the accumulation of PrP(Sc), an abnormally folded isoform of the cellular prion protein

BOLL‐Containing Aggregates Mediate the Translational Regulation During Human Oogenesis

Cell Proliferation, EarlyView.
This work elucidates that BOLL‐containing aggregate‐mediated translational control is essential for human oogenesis. These aggregates recruit PABPC1 and FXR1 to activate the translation of U‐rich mRNAs encoding cell cycle proteins, thereby ensuring successful meiotic progression.

MAVS oligomerization drives a faster and more efficient antiviral signaling activation at peroxisomes compared to mitochondria

The FEBS Journal, EarlyView.
Cells rely on mitochondria and peroxisomes to trigger antiviral defenses via the protein MAVS. This manuscript demonstrates that the robust production of antiviral effectors resulting from MAVS activation at peroxisomes is faster than at mitochondria due to a swifter oligomerization of this protein at peroxisomal membranes. These results underscore the

Small critical RNAs in the scrapie agent [PDF]

, 2009
Unconventional infectious agents cause transmissible spongiform encephalopathy (TSE) diseases including scrapie and bovine spongiform encephalopathy (BSE) in animals and Creutzfeldt-Jakob disease in humans. The protein only hypothesis claims that the TSE

Redox environment modulates aggregation of ataxin‐3 in vitro — Implications for drug screening of cysteine‐rich proteins

The FEBS Journal, EarlyView.
Redox environment modulates in vitro aggregation of Ataxin‐3, the protein implicated in spinocerebellar ataxia type 3. Reducing conditions stabilize native monomers and prevent aggregation, whereas oxidative conditions promote the formation of non‐native conformers and disulfide‐linked oligomers within the Josephin domain (JD).

Proteostasis of organelles in aging and disease

The FEBS Journal, EarlyView.
Cells rely on regulated proteostasis mechanisms to keep their internal compartments functioning properly. When these mechanisms fail, damaged proteins accumulate, disrupting organelles, such as the nucleus, mitochondria, endoplasmic reticulum, Golgi, and lysosomes, as well as membraneless organelles, such as stress granules, processing bodies, the ...

A receptor for infectious and cellular prion protein [PDF]

Brazilian Journal of Medical and Biological Research, 1999
Prions are an unconventional form of infectious agents composed only of protein and involved in transmissible spongiform encephalopathies in humans and animals. The infectious particle is composed by PrPsc which is an isoform of a normal cellular glycosyl-phosphatidylinositol (GPI) anchored protein, PrPc, of unknown function.

Bone Grafts: Everything You Need to Know

Journal of Periodontal Research, EarlyView.
This review classifies bone grafts (autograft, allograft, xenograft, synthetic) by source and osteogenic/inductive/conductive potential, linking material properties and mechanisms to clinical indications in periodontal and dental regeneration. Key challenges—limited osteoinduction, poor vascularisation, unbalanced resorption, handling difficulties, and

Japan Brain Bank Net (JBBN)

Psychiatry and Clinical Neurosciences, EarlyView.
Autopsies have long been performed to determine the cause of death in the medical field. In fact, autopsies have significantly contributed to our understanding of neurological and psychiatric disorders. Patients and their families who wish to donate bodies for autopsy may have various expectations, such as contributing to the development of treatments ...

Long‐term stability of horizontal bone augmentation at implant sites

Periodontology 2000, EarlyView.
Abstract Horizontal bone augmentation is a fundamental surgical procedure in regenerative implant dentistry. In recent decades, this procedure has evolved, enabling clinicians to achieve predictable and stable horizontal bone augmentation that supports dental implant restorations.
