Current schedule: Mondays @12:00 noon ESTThe invited lectures on Proteinopathies will take place via Zoom. After a brief introduction of the speaker by a moderator (<2 minutes), the invited speaker will present the lecture for 25-30 minutes followed by a question-and-answer session led by the moderator (for ~15 minutes). Lectures will be recorded to allow offline viewing, but the recording will be turned off at the speaker's preference. To facilitate the question-and-answer session, the audience will be invited to submit questions during the lecture using the Q&A folder in Zoom. After the lecture, the moderator will read the questions to the speaker (or a subset of related questions) and if needed unmute a participant for follow-up discussion. Depending on the availability of the speaker, the informal discussion may continue for ~20 minutes after the formal session.
If you are an expert in the following area(s) and wish to give a talk, please contact us.

A Hypothesis for How Innate Immune Dysregulation May Cause Alzheimer’s Dementia;
A Hypothesis for How Innate Immune Dysregulation May Cause Alzheimer’s Dementia;
and How We May Be Able to Prevent It
and How We May Be Able to Prevent It
We are investigating the early-stage etiology of sporadic Alzheimer's Disease (AD), for which 420+ clinical trials by Pharma have failed over the past 15 years to produce an effective drug. What causes the accumulation of Aβ peptide-rich fibrils and plaques in an aging brain? What are Aβ's physiological functions? We focus on Aβ's interactions with the human cathelicidin peptide, LL-37, an antibacterial and antiviral innate immune system effector and modulator that is ubiquitous in tissues and expressed by myriad cell types, yet unique in the human proteome. Recently, evidence has built that chronic Herpesvirus or P. gingivalis infections of human brain tissue may precipitate many cases of sporadic dementia labeled as Alzheimer’s Disease. We present experimental evidence and discuss our developing hypothesis that the antiviral and antibacterial peptide LL-37, which can be chronically under-expressed in humans based on dietary and lifestyle factors or degraded by P. gingivalis virulence factors, is a natural binding partner of Aβ that inhibits formation of AD fibrils and plaques, such that LL-37 and Aβ have a toxin/antitoxin relationship. We demonstrate binding between LL-37 and Aβ by Transmission Electron Microscopy (TEM), Surface Plasmon Resonance Imaging (SPRi), and circular dichroism (CD) spectroscopy. TEM shows that LL-37 inhibits the fibrillization of Aβ, especially the formation of long, straight fibrils characteristic of AD, while CD spectroscopy reveals that LL-37 binding prevents Aβ from adopting β-type secondary structure. Analytical Ultracentrifugation (AUC) and Small-Angle X-ray Scattering (SAXS) prove that LL-37 and Aβ form a unique, water-soluble, 1:1 complex. In vitro cell culture studies using primary human microglia and neuronal cells indicates that these two peptides neutralize each other’s cytotoxic effects on these cells. Finally, studies in 5XFAD and wildtype transgenic mice, and Drosophila Melanogaster, support these findings. We discuss what all of this means in the context of the prevention and treatment of Alzheimer’s dementia.

“Specific viral RNA drives the SARS CoV-2 nucleocapsid to phase separate "
A mechanistic understanding of the SARS-CoV-2 viral replication cycle is essential to develop new therapies for the COVID-19 global health crisis. In this study, we show that the SARS-CoV-2 nucleocapsid protein (N-protein) undergoes liquid-liquid phase separation (LLPS) with the viral genome, and propose a model of viral packaging through LLPS. N-protein condenses with specific RNA sequences in the first 1000 nts (5’-End) under physiological conditions and is enhanced at human upper airway temperatures. N-protein condensates exclude non-packaged RNA sequences. We comprehensively map sites bound by N-protein in the 5’-End and find preferences for single-stranded RNA flanked by stable structured elements. Liquid-like N-protein condensates form in mammalian cells in a concentration-dependent manner and can be altered by small molecules. Condensation of N-protein is sequence and structure specific, sensitive to human body temperature, and manipulatable with small molecules thus presenting screenable processes for identifying antiviral compounds effective against SARS-CoV-2.

The thermodynamic hypothesis of protein folding, known as the “Anfinsen’s dogma” states that the native structure of a protein represents a free energy minimum determined by the amino acid sequence. However, inconsistent with the Anfinsen’s dogma, globular proteins can misfold to form amyloid fibrils, which are ordered aggregates associated with diseases such as Alzheimer’s and Parkinson’s diseases. Here, we present a general concept for the link between folding and misfolding. We tested the accessibility of the amyloid state for various proteins upon heating and agitation. Many of them showed Anfinsen-like reversible unfolding upon heating, but formed amyloid fibrils upon agitation at high temperatures. We show that folding and amyloid formation are separated by the supersaturation barrier of a protein. Its breakdown is required to shift the protein to the amyloid pathway. Thus, the breakdown of supersaturation links the Anfinsen’s intramolecular folding universe and the intermolecular misfolding universe.

“Probing toxic protein oligomers: From test tubes to patient-derived neurons”
“Probing toxic protein oligomers: From test tubes to patient-derived neurons”
Understanding how amyloid aggregates actually become toxic is one of the challenges in developing a treatment for diseases such as Alzheimer’s and Parkinson’s. One of the major possibilities is that the small oligomeric aggregates incorporate into the cell membrane and make specific functional structures which ultimately cause toxicity. However, very little is known about the structure of the oligomers, the stoichiometry of the toxic oligomer, its insertion into the membrane, and subsequent cellular interactions. Perhaps the hardest problem is to establish the correlation of all these parameters with the actual disease. Here we address these issues for Amyloid-beta, which is associated with Alzheimer’s disease. Nature has provided some clues for Alzheimer’s in terms of the location of disease-accelerating mutations, correlations with other protein isoforms, and neuron-type specific vulnerabilities. However, they have been hard to interpret. Using tools such as nanosecond FCS, time resolved FRET, solid state NMR, membrane-mediated SERS, single molecule photobleaching, and Alzheimer’s patient-derived neurons, we are finally making sense of some of these clues.

“Role of α-synuclein phosphorylation at serine 129 in the pathogenesis of synucleinopathies: an active debate"
“Role of α-synuclein phosphorylation at serine 129 in the pathogenesis of synucleinopathies: an active debate"
Parkinson’s disease (PD) and dementia with Lewy bodies (DLB) are human neurodegenerative diseases characterized neuropathologically by the presence of neuronal α-synuclein inclusions, named as Lewy bodies and Lewy neurites. Increasing number of studies highlighted the aberrant accumulation of phosphorylated α-synuclein at the residue Serine129 (pS129) in the brain of PD and DLB patients, suggesting that phosphorylation may play a vital role in the regulation of α-synuclein aggregation and subsequent neuronal degeneration. However, a comprehensive understating of the exact role of α-synuclein phosphorylation at S129 is still lacking. Here, we study the time-point at which pS129 modification occurs in the process of α-synuclein aggregation and its role in initiation, progression and cellular toxicity of the disease. Therefore, with the collaboration of many international teams we have addressed this issue by designing and executing important in vitro, ex vivo, and in vivo experiments using various models, in addition to post-mortem human brain studies. Contrary to the putative view of pS129-α-synuclein being particularly disease-relevant form of α-synuclein, we suggest that pS129 diminished aggregation-propensity, attenuated cytotoxicity, and occurs subsequent to initial α-synuclein aggregation. Our novel findings have important implications for the design of future neuropathological studies and the development of therapeutic approaches targeting of distinct α-synuclein species.
