Early-life vitamin A treatment rescues neonatal infection-induced durably impaired tolerogenic properties of celiac lymph nodes

Gut -draining mesenteric and celiac lymph nodes (mLNs and celLNs) critically contribute to peripheral tolerance toward food and microbial antigens by supporting the de novo induction of regulatory T cells (Tregs). These tolerogenic properties of mLNs and c ...

A Cluster of Evolutionarily Recent KRAB Zinc Finger Proteins Protects Cancer Cells from Replicative Stress–Induced Inflammation

Didier Trono, Priscilla Turelli, Sandra Eloise Kjeldsen, Evaristo Jose Planet Letschert, Filipe Amândio Brandão Sanches Vong Martins, Florian Huber, Cyril David Son-Tuyên Pulver, Olga Marie Louise Rosspopoff, Romain Forey, Joana Carlevaro Fita

Heterochromatin loss and genetic instability enhance cancer progression by favoring clonal diversity, yet uncontrolled replicative stress leads to mitotic catastrophe and inflammatory responses that promote immune rejection. KRAB domain-containing zinc fin ...

Human alveolar lining fl uid from the elderly promotes Mycobacterium tuberculosis intracellular growth and translocation into the cytosol of alveolar epithelial cells

Richa Mishra, Vivek Vijay Thacker

The elderly population is highly susceptible to developing respiratory diseases, including tuberculosis, a devastating disease caused by the airborne pathogen Mycobacterium tuberculosis ( M.tb ) that kills one person every 18 seconds. Once M.tb reaches the ...

Multimodal transcriptomic atlases of mouse spinal cord injury

Matthieu Pierre Gautier

A spinal cord injury (SCI) triggers a cascade of molecular and cellular responses involving inflammatory cell infiltration and cytokine release, apoptosis, demyelination, excitotoxicity, ischemia, and the formation of a fibrotic scar surrounded by an astro ...

Exploring the role of cGAS-STING-mediated inflammation in age-associated neurodegeneration and antitumor immunity

Natasha Ella Samson

Inflammation stands as a dynamic and intricate biological process, promoting vital defence mechanisms against harmful stimuli, including infections and injuries, to drive pathogen clearance and healing. On one hand, these responses can manifest acutely and ...

The CRL5-SPSB3 ubiquitin ligase targets nuclear cGAS for degradation

Andrea Ablasser, Baptiste Claude André Guey, Jonathan Jean-Pierre Ricci, Chong Liu, Pauline Ambre Melenec, Pengbiao Xu, Lingyun Li, Ying Liu

Cyclic GMP-AMP synthase (cGAS) senses aberrant DNA during infection, cancer and inflammatory disease, and initiates potent innate immune responses through the synthesis of 2 ' 3 '-cyclic GMP-AMP (cGAMP)1-7. The indiscriminate activity of cGAS towards DNA d ...

The conceptual foundations of innate immunity: Taking stock 30 years later

Bruno Lemaitre

While largely neglected over decades during which adaptive immunity captured most of the attention, innate immune mechanisms have now become central to our understanding of immunology. Innate immunity provides the first barrier to infection in vertebrates, ...

Methanobrevibacter smithii ( m. smithii) for use as a biomarker and in the diagnosis and the treatment of disorders associated with aberrant microbiota and/or archaea-deficiency

Duncan-Bruce Sutherland

The present invention generally relates to the field of intestinal health, disorders associated with aberrant microbiota and/or archaea-deficiency, and early-life immune system development. The present invention more specifically relates to M. smithii and ...

KRAB zinc finger proteins link heterochromatin maintenance to replicative stress and inflammation in diffuse large B-cell lymphoma

Filipe Amândio Brandão Sanches Vong Martins

Genomic instability enhances cancer progression by favoring clonal diversity, yet uncontrolled replicative stress can lead to mitotic catastrophe and inflammatory responses promoting immune rejection. KRAB-containing zinc finger proteins (KZFPs) are epigen ...

Redox and Immune Signaling in Schizophrenia: New Therapeutic Potential

Lijing Xin, Kim Do, Daniella Dwir

Redox biology and immune signaling play major roles in the body, including in brain function. A rapidly growing literature also suggests that redox and immune abnormalities are implicated in neuropsychiatric conditions such as schizophrenia (SZ), bipolar d ...
