This study aimed to investigate the effects of lipopolysaccharide (LPS)-induced chronic immune stress on intestinal morphology and function, immune system, oxidative status, and mitochondrial function in piglets. Fifty healthy Duroc × Landrace × Yorkshire piglets (21 ± 2 days old, barrow, 6.98 ± 0.14 kg body weight) were selected and randomly allotted to five groups, which were slaughtered at 0 (0 group), 1, 5, 9, and 15 d of LPS injection. The results showed that compared with the piglets without LPS injection, LPS injection significantly impaired the intestinal morphology and permeability at 1, 5, and 9 d, as manifested by the increased serum lactic acid and decreased ratio of villus height to crypt depth (p < 0.05). Moreover, intestinal inflammation and oxidative and mitochondrial injury were caused at 1 d, as manifested by upregulated IL-6 mRNA expression, increased malondialdehyde content, and impaired mitochondrial morphology (p < 0.05). However, these parameters were restored to levels identical to 0 group at 9~15 d, accompanied by significantly increased antioxidant capacity, enhanced protein expression of CD3+ and CD68+, and upregulated mRNA abundance of genes related to mitochondrial biogenesis and functions (p < 0.05). Collectively, these results suggest that the intestinal injury of piglets caused by chronic immune stress could be self-repaired.

Background: Mixed-species, mixed-strain plasmodia infections are known to occur in humans in malaria endemic areas. It may be surprising that to date, the extent of this complexity has not been systematically explored in high-burden countries of sub-Saharan Africa, especially in the reservoir of asymptomatic infections in all ages, which sustains transmission.
Methods: Here we take a metagenomic lens to these infections by sampling variable blood volumes from 188 afebrile residents living in high, seasonal transmission in Northern Sahelian Ghana.

Atherosclerosis, a major cause of cardiovascular diseases, is characterized by the buildup of lipids and chronic inflammation in the arteries, leading to plaque formation and potential rupture. Despite recent advances in single-cell transcriptomics (scRNA-seq), the underlying immune mechanisms and transformations in structural cells driving plaque progression remain incompletely defined. Existing datasets often lack comprehensive coverage and consistent annotations, limiting the utility of downstream analyses.

Introduction: Many women of childbearing age are being treated for chronic conditions that require long-term medication. We assessed the knowledge of women being treated in internal medicine and clinical immunology, regarding the impact of their disease and specific treatments on a potential pregnancy.
Methods: Between September 1st, 2019, and November 1st, 2020, in four hospitals in the Poitou-Charentes region, a questionnaire was given to every woman aged 18 to 44 who came in for an internal medicine and clinical immunology consultation for the follow-up of a chronic systemic disease.

Autoimmune diseases arise from genetic and environmental factors that disrupt immune tolerance. Recent studies highlight the role of myeloid cell immunometabolism, particularly mitochondrial dysfunction, in driving autoimmunity. Mitochondria regulate energy homeostasis and cell fate; their impairment leads to defective immune cell differentiation, abnormal effector activity, and chronic inflammation.

Multiple sclerosis (MS) is a chronic inflammatory disease of the central nervous system (CNS) that is characterized by a severe and progressive demyelinating process. It is considered a neurodegenerative autoimmune disorder driven by immune cell infiltration, overproduction of cytokines and reactive oxygen species (ROS) accumulation that leads to axonal and neuronal injury. Experimental autoimmune encephalomyelitis (EAE) is the most commonly used pre-clinical model of multiple sclerosis (MS), since it resembles many aspects of the human disease.
