Article Abstract

Research Question: What is the potential role of immune cells and their inflammatory cytokines in the pathogenesis, development and establishment of endometriosis?

Design: Peritoneal fluid from 59 women (43 with endometriosis and 16 controls) who had undergone laparoscopic surgery was analysed. Changes in the population of innate and adaptive immune cells, cytokines, chemokines and growth factor expression were measured by flow cytometry, Luminex Technology and enzyme-linked immunosorbent assay.

Results: No differences were found in the frequencies of the innate and adaptive immune cells between women with and without endometriosis. In the peritoneal fluid of women with endometriosis, IL-1β, IL-1RN, IL-2, IL-4, IL-8, IL-10, IL-12 (p70), IL-17α, FGF2, G-CSF, MCP-1, MIP-1α and TNF-α were significantly increased compared with controls. A correlation between IL-2, MCP-1, MIP-1α, TNF-α and the severity of endometriosis was observed. The concentration of neopterin, a possible biomarker for this disease, was increased in women with endometriosis compared with controls.

Conclusions: The functional activity of immune cells seemed to be reduced despite their numbers remaining unchanged. The data indicate that a shift of T cytokine profile occurs, which increases the T1-T2 ratio. This is driven by the increased levels of the cytokines (TNF-α and IL-2) in women with severe endometriosis.

Type 1 diabetes (T1D) is an autoimmune chronic disease that leads to the destruction of pancreatic beta cells and thus requires lifelong insulin therapy. Constraints and adverse events associated to insulin therapy are well known as well as the risk of long-term complications linked to chronic hyperglycaemia. Symptomatic T1D is preceded by a preclinical asymptomatic period, which is characterized by the presence of at least two auto-antibodies against beta cell without disturbances of blood glucose control (stage 1) or, in addition to immunological biomarkers, by the presence of mild dysglycaemia reflecting a defect of early insulin secretion (stage 2).

Microglia, the resident immune cells of the central nervous system (CNS), are involved in the pathogenesis of neurodegenerative diseases, such as Alzheimer's disease (AD), Dementia with Lewy Bodies (DLB), and Parkinson's disease (PD). 14-3-3 proteins act as molecular hubs to regulate protein-protein interactions, which are involved in numerous cellular functions, including cellular signaling, protein folding, and apoptosis. We previously revealed decreased 14-3-3 levels in the brains of human subjects with neurodegenerative diseases.

Aims: Sustained neuroinflammation following ischemic stroke impedes post-injury tissue repairment and neurological functional recovery. Developing innovative therapeutic strategies that simultaneously suppress detrimental inflammatory cascades and facilitate neurorestorative processes is critical for improving long-term rehabilitation outcomes.

Methods: We employed a microglia depletion-repopulation paradigm by administering PLX5622 for 7 days post-ischemia; followed by a 7-day withdrawal period to allow microglia repopulation.

Background: Recent research has started to uncover an important connection between immune system activity and cognitive abilities. Although correlative associations have been documented, the causal mechanisms connecting specific immune cell subpopulations to cognitive capabilities remain insufficiently characterized. Our research aimed to determine directional relationships between distinct immune cell subtypes and cognitive function, potentially identifying targets for immunomodulatory interventions.

TOX-induced lnc-SUMF2-8 compromises antitumor function and anti-PD-1 response of CD8 T cells via lysosome-dependent degradation of TCF-1.

The reduction of TCF-1 during CD8 T cell exhaustion leads to attenuated antitumor activity and diminished responsiveness to immune checkpoint inhibitors. However, how TCF-1 is downregulated remains unclear. Here, we showed that during CD8 T cell exhaustion, lnc-SUMF2-8, induced by transcription factor TOX, can bind to cytosolic TCF-1, and direct it to the lysosome for degradation.
