Immunology of Aging: the Birth of Inflammaging

T. Fulop, A. Larbi, G. Pawelec, A. Khalil, A. A. Cohen, K. Hirokawa, J. M. Witkowski, C. Franceschi

Summary: The concept of inflammaging introduced by Prof. Franceschi in 2000 revolutionized the understanding of immune changes in response to lifelong stress. It highlights the dichotomy of the proinflammatory process, influenced by genetics and the environment, leading to either beneficial or detrimental consequences. Moreover, it elucidates the complex and systemic nature of aging, opening avenues for studying counter-processes in addition to the process itself. This concept also paves the way for potential multimodal interventions to optimize aging towards healthy longevity.

Summary: Environmental exposure plays a major role in the development of allergic diseases, including climate change, pollution, changes and loss of biodiversity, etc. The epithelial barrier hypothesis provides a mechanistic explanation of how these factors contribute to the increase in allergic and autoimmune diseases. Measures should be taken to mitigate environmental threats and decrease allergic diseases.

Summary: A novel autoinflammatory syndrome called VEXAS has been discovered in male patients with somatic mutations in the UBA1 gene. This study retrospectively diagnosed VEXAS in previously unclassified autoinflammatory patients and described the clinical experiences with this complex disease. Through reanalysis of whole-exome sequencing data, 12 male patients with UBA1 mutations were identified. These patients experienced adult-onset autoinflammation with systemic symptoms, elevated inflammatory parameters, and multiorgan involvement, particularly affecting the skin and bone marrow. New features of VEXAS included interstitial nephritis, cardiac involvement, stroke, and intestinal perforation related to tocilizumab treatment. Despite various treatments, most patients were treatment-refractory, leading to a high mortality rate of 50%.

Summary: This research searched for evidence on how different physicochemical properties affect the allergenicity of food proteins, and found consistent effects on protein allergenicity within the same protein family. Molecular stability was identified as the most common characteristic promoting plant protein allergenicity. However, there is still a lack of systematic approach to link physicochemical properties with clinical allergenicity.

Summary: The study of chronic rhinosinusitis (CRS) has shifted from phenotype-based classification to endotype-based classification, identifying three main endotypes that orchestrate the expression of different gene sets. The development of improved methods for endotyping disease is expanding the use of biological therapies, targeting Type 2 inflammation and potentially other inflammatory endotypes in the future.

Subtypes of atopic dermatitis: From phenotype to endotype

Yoshiki Tokura, Satoshi Hayano

Summary: Atopic dermatitis (AD) is a heterogeneous disorder that can be classified into different types, including the IgE-high, extrinsic subtype and the IgE-normal, intrinsic subtype. Recent research has shown that different populations have different AD subtypes, which differ in immune regulation, skin barrier, and cytokine activation. Therefore, personalized or precision medicine is crucial for the treatment of AD targeting each subtype.
