Novel Insights into the Role of Defensins in Virus-Induced Autoimmunity in the Central Nervous System

Journal of Neuroinfectious Diseases (2016)

Evangelos Kazakos Jannis Kountouras

Virus-induced autoimmunity in the brain, an immune-privileged site, occurs primarily from a breach in thymic selection mechanisms that constitute peripheral tolerance, culminating in a self-directed, Tcell- mediated immune response traditionally thought to occur via molecular or epitope mimicry; immune recognition of novel selfantigens; bystander activation of autoreactive defensin-specific, Tlymphocytes (ATLs); and aberrant expression of cytokines in polyclonically expanded T-cell subsets.

Epic-Sounds: A Large-scale Dataset of Actions That Sound

arXiv (Cornell University) (2023)

Jaesung Huh Jacob Chalk Evangelos Kazakos Dima Damen Andrew Zisserman

We introduce EPIC-SOUNDS, a large-scale dataset of audio annotations capturing temporal extents and class labels within the audio stream of the egocentric videos. We propose an annotation pipeline where annotators temporally label distinguishable audio segments and describe the action that could have caused this sound. We identify actions that can be discriminated purely from audio, through grouping these free-form descriptions of audio into classes. For actions that involve objects colliding, we collect human annotations of the materials of these objects (e.g. a glass object being placed on a wooden surface), which we verify from visual labels, discarding ambiguities. Overall, EPIC-SOUNDS includes 78.4k categorised segments of audible events and actions, distributed across 44 classes as well as 39.2k non-categorised segments. We train and evaluate two state-of-the-art audio recognition models on our dataset, highlighting the importance of audio-only labels and the limitations of current models to recognise actions that sound.

Impact of Helicobacter pylori and metabolic syndrome-related mast cell activation on cardiovascular diseases

Frontiers in Gastroenterology (2024)

Michael Doulberis Apostolis Papaefthymiou Stergios A. Pοlyzos Marina Boziki Evangelos Kazakos

Helicobacter pylori , a widely renowned bacterium, has recently gained attention owing to its potential impact on extragastric health. The emergence of research linking H. pylori infection with metabolic syndrome (MetS)-related cardiovascular diseases (CVDs) has raised intriguing questions about the pathogenic linkage and its translational implications for clinicians. MetS encompasses a collection of metabolic abnormalities that considerably elevate the risk of CVDs and cerebrovascular diseases. Emerging evidence supports a potential pathogenetic role of H. pylori for MetS-related disorders through mechanisms implicating chronic smoldering inflammation, insulin resistance (IR), and modulation of immune responses. One intriguing aspect of this possible connection is the role of mast cells (MCs), a subset of immune cells representing innate immune system effector cells. They play a fundamental role in innate immune responses and the modulation of adaptive immunity. Activated MCs are commonly found in patients with MetS-related CVD. Recent studies have also suggested that H. pylori infection may activate MCs, triggering the release of pro-inflammatory mediators that contribute to IR and atherosclerosis. Understanding these intricate interactions at the cellular level provides new insights into the development of therapeutic strategies targeting both H. pylori infection and MetS-related MCs activation. This review investigates the current state of research regarding the potential impact of H. pylori infection and MetS-related MCs activation on the pathophysiology of CVD, thereby opening up new avenues for related research and paving the way for innovative approaches to prevention and treatment in clinical practice

EPIC-Fusion: Audio-Visual Temporal Binding for Egocentric Action Recognition

Evangelos Kazakos Arsha Nagrani Andrew Zisserman Dima Damen

We focus on multi-modal fusion for egocentric action recognition, and propose a novel architecture for multi-modal temporal-binding, i.e. the combination of modalities within a range of temporal offsets. We train the architecture with three modalities -- RGB, Flow and Audio -- and combine them with mid-level fusion alongside sparse temporal sampling of fused representations. In contrast with previous works, modalities are fused before temporal aggregation, with shared modality and fusion weights over time. Our proposed architecture is trained end-to-end, outperforming individual modalities as well as late-fusion of modalities. We demonstrate the importance of audio in egocentric vision, on per-class basis, for identifying actions as well as interacting objects. Our method achieves state of the art results on both the seen and unseen test sets of the largest egocentric dataset: EPIC-Kitchens, on all metrics using the public leaderboard.
