Objective: To obtain precise data on the changes in the levels of 29 cytokines in mice after high or low linear energy transfer (LET) irradiation and to develop an accurate model of radiation exposure based on the cytokine levels after irradiation.
Methods: Plasma samples harvested from mice at different time points after carbon-ion or X-ray irradiation were analyzed using meso-scale discovery (MSD), a high-throughput and sensitive electrochemiluminescence measurement technique. Dose estimation equations were set up using multiple linear regression analysis.
Results: The relative levels of IL-6 at 1 h, IL-5 and IL-6 at 24 h, and IL-5, IL-6 and IL-15 at 7 d after irradiation with two intensities increased dose-dependently. The minimum measured levels of IL-5, IL-6 and IL-15 were up to 4.0076 pg/mL, 16.4538 pg/mL and 0.4150 pg/mL, respectively. In addition, dose estimation models were established and verified.
Conclusions: The MSD assay can provide more accurate data regarding the changes in the levels of the cytokines IL-5, IL-6 and IL-15. These cytokines could meet the essential criteria for radiosensitive biomarkers and can be used as radiation indicators. Our prediction models can conveniently and accurately estimate the exposure dose in irradiated organism.

Cortical thickness correlated with peripheral inflammatory cytokines in amyotrophic lateral sclerosis.

Introduction: Amyotrophic lateral sclerosis (ALS) is a rare, devastating neurodegenerative disease that affects upper and lower motor neurons, resulting in muscle atrophy, spasticity, hyperreflexia, and paralysis. Inflammation plays an important role in the development of ALS, and associated with rapid disease progression. Current observational studies indicate the thinning of cortical thickness in patients with ALS is associated with rapid disease progression and cognitive changes.

The impact of human cytomegalovirus (HCMV) infection on the mid- and long-term balance between pro-inflammatory and anti-inflammatory cytokines among kidney transplant recipients (KTRs) remains unclear. We measured plasma levels of 12 Th1/Th2-type cytokines (granulocyte-macrophage colony-stimulating factor, interferon-γ, interleukin [IL]-1β, IL-2, IL-4, IL-5, IL-6, IL-10, IL-12p70, IL-13, IL-18 and tumor necrosis factor-α) in a cohort of 290 KTRs at four time points through month 12 after transplantation. Cytokine levels at each point were compared according to the previous documentation of HCMV replication by two approaches: "cumulative exposure" from the time of transplantation and "recent exposure" within the 2-3 months preceding cytokine assessment.

This study investigated time-dependent changes in intracellular Ca⁺ levels in T cells, regulatory mechanisms, and functional effects after acute exercise. Male C57BL/6 mice were assigned to control and exercise groups, with the latter sacrificed at different intervals post-exercise. Murine splenic lymphocytes were isolated, and cytosolic Ca⁺ levels were measured using Fluo-3/AM.

Purpose: To investigate whether sub-Tenon injection of triamcinolone acetonide (STTA) combined with anti-vascular endothelial growth factor (VEGF) prolongs the recurrence intervals of macular edema (ME) for chronic retinal vein occlusion (RVO) and to investigate the differences in intraocular inflammatory cytokines between good responders (GRs) and non-responders (NRs).
Methods: This retrospective, observational study involved 42 eyes of 42 patients with ME due to chronic RVO who had received only anti-VEGF for ≥ 1 year and were transitioned to combination therapy. GRs were defined as patients whose recurrence intervals were prolonged by ≥ 2 weeks compared with patients receiving anti-VEGF alone.
