The immune system is designed to protect the organism from infection and to repair damaged tissue. An effective response requires recognition of the threat, the appropriate effector mechanism to clear the pathogen and a return to homeostasis with minimal damage to self-tissues. T cells play a central role in orchestrating the immune response at all stages of the response and have been the subject of intense study by both experimental immunologists and modelers. This review examines some of the more critical questions in T cell biology and describes the latest attempts to address those questions using approaches that combine mathematical modeling and experiments.

Purpose Of Review: This review explores the evolving understanding of efferocytosis - the clearance of dead or dying cells by phagocytes - in the context of atherosclerosis. It highlights recent discovers in cell death modalities, impaired clearance mechanisms and emerging therapeutic strategies aimed at restoring efferocytosis to stabilize plaques and resolve inflammation.
Recent Findings: Recent studies have expanded the scope of efferocytosis beyond apoptotic cells to include other pro-inflammatory cell death modes, including pyroptosis, necroptosis and ferroptosis, revealing context-dependent clearance efficiency and immunological outcomes.

Adenosine A receptors (AARs) have shown promising therapeutic properties despite their controversial role in modulating stroke outcome. However, the temporal evolution of cerebral AARs density after cerebral ischemia and its subsequent neuroinflammatory response have been scarcely explored. In this study, the expression of AARs after transient middle cerebral artery occlusion (MCAO) was evaluated in rats by positron emission tomography (PET) with [C]SCH442416 and immunohistochemistry (IHC).

Purpose Of Review: Autoimmune nodopathies (AN) are a recognized distinct group of immune-mediated peripheral neuropathies with unique immunopathological features and therapeutic implications. This review synthesizes recent advances in their pathogenesis, diagnosis, and management, which have refined their clinical classification and informed targeted treatment strategies.
Recent Findings: AN are characterized by autoantibodies targeting surface proteins in the nodal-paranodal area (anti-contactin-1, anti-contactin-associated protein 1, anti-neurofascin-155, anti-pan-neurofascin), predominantly of IgG4 subclass.
Macrophage Migration Inhibitory Factor (MIF) is a pleiotropic cytokine that acts as a central regulator of inflammation and immune responses across diverse organ systems. Functioning upstream in immune activation cascades, MIF influences macrophage polarization, T and B cell differentiation, and cytokine expression through CD74, CXCR2/4/7, and downstream signaling via NF-κB, ERK1/2, and PI3K/AKT pathways. This review provides a comprehensive analysis of MIF's mechanistic functions under both physiological and pathological conditions, highlighting its dual role as a protective mediator during acute stress and as a pro-inflammatory amplifier in chronic disease.

Vibrio infections cause enteritis in grouper fish, leading to high mortality and stunted growth, which is a major challenge for aquaculture. Oligochitosans, marine prebiotics with bioactive properties, have proven their potential for growth promotion and immune regulation. However, the impacts of Vibrio harveyi on the gut microbiome of grouper fish and the potential of oligochitosans to modulate these effects remain poorly understood.
