Interest in intestinal mononuclear phagocytes (MPs), both DCs and macrophages (Mφs), has exploded in the recent years. In this Viewpoint we will detail how resident intestinal lamina propria (LP) Mφs possess distinctive properties that reflect adaptation to a unique microenvironment. They play quite different roles in the normal and inflamed mucosa and, as we will show, the existing paradigms of differentiated Mφ subsets and of 'resident' versus 'inflammatory' monocytes based on other tissues may not apply to the gut. Strategies for targeting Mφs as a means of dampening intestinal inflammation will need to take account of these unique characteristics.

Sigma1 inhibitor suppression of adaptive immune resistance mechanisms mediated by cancer cell derived extracellular vesicles.

Adaptive immune resistance in cancer describes the various mechanisms by which tumors adapt to evade anti-tumor immune responses. IFN-γ induction of programmed death-ligand 1 (PD-L1) was the first defined and validated adaptive immune resistance mechanism. The endoplasmic reticulum (ER) is central to adaptive immune resistance as immune modulatory secreted and integral membrane proteins are dependent on ER.

Artificial fish nests are common tools in fisheries management, providing spawning grounds to enhance the size and diversity of fish populations. This study aimed to explore the effects of deployment locations on the reproductive efficiency and preferences of fish with adhesive and demersal eggs using artificial nests. Floating artificial nests were deployed in three regions (upstream, midstream, and downstream) of a reservoir in Zhejiang, China, at locations with three topographical types: steep slope (reservoir shore, slopes > 60°), gentle slope (reservoir shore, slopes < 30°), and confluence (middle thread of channel).

Objective: Metabolic reprogramming plays a critical role in modulating the innate and adaptive immune response, but its role in cutaneous autoimmune diseases, such as cutaneous lupus erythematosus (CLE), is less well studied. An improved understanding of the metabolic pathways dysregulated in CLE may lead to novel treatment options, biomarkers and insights into disease pathogenesis. The objective was to compare metabolomic profiles in the skin and sera of CLE and control patients using liquid chromatography-mass spectrometry (LC-MS).

Objective: Extracting named entities from clinical free-text presents unique challenges, particularly when dealing with discontinuous entities-mentions that are separated by unrelated words. Traditional NER methods often struggle to accurately identify these entities, prompting the development of specialised computational solutions. This paper systematically reviews and presents the methodologies developed for Discontinuous Named Entity Recognition in clinical texts, highlighting their effectiveness and the challenges they face.

Background: Aging increases disease susceptibility and reduces vaccine responsiveness, highlighting the need to better understand the aging immune system and its clinical associations. Studying the human immune system, however, remains challenging due to its complexity and significant inter-individual variability.
Methods: We conducted an immune profiling study of 550 elderly participants (≥60 years) and 100 young controls (20-40 years) from the RESIST Senior Individuals (SI) cohort.
