Aim: To analyze the expression levels of soluble form of CD95, CD95 ligand (sCD95 and sCD95L, respectively) in plasma and CD95 expression on CD3+ cells in liver-transplanted recipients with acute rejection (AR).
Methods: Peripheral blood mononuclear cells (PBMCs) were isolated from 30 clinically liver transplanted recipients. CD95 expression on CD3+ cells was quantitatively measured by two-color fluorescence activated cell sorter (FACS) analysis. Lymphocyte surface phenotypes of CD4, CD8, CD16 and CD56 were determined by flow cytometry. Plasma levels of sCD95 and sCD95L were detected by Enzyme Linked-Immuno-Sorbent Assay (ELISA). The results were compared with that from normal healthy volunteers (n = 15 individuals).
Results: FACS analysis showed that CD95 expression on CD3+ T cells was significantly increased in liver transplanted recipients with AR compared to that in stable recipients without rejection and infection or healthy individuals who did not undergo transplantation (18,676.93+/-11,588.34/molecule, 6,848.20+/-1 712.96/molecule, 6,418.01+/-2,001.95/molecule, respectively, P<0.01). Whereas no significant difference was seen between liver-transplanted stable recipients and healthy individuals. Furthermore, no significant differences were detected between each group with CD4/CD8 ratio or the percentage of CD16+56+ cells. Plasma levels of sCD95 were significantly higher in transplanted recipients with AR compared to that in stable recipients or healthy individuals (391.88+/-196.00, 201.37+/-30.30, 148.83+/-58.25 pg/mL, respectively, P<0.01). In contrast, the plasma levels of sCD95L in liver- transplanted recipients were not significantly different from that in healthy individuals.
Conclusion: The present results indicate that the increased CD95 expression on CD3+ cells and the increased levels of sCD95 in plasma may modify the immunological situation of the recipients after transplantation or represent the ongoing graft rejection.

Background: Disialoganglioside (GD2) is a tumor-associated antigen that is highly expressed in various neuroectodermal cancers, including melanoma. While chimeric antigen receptor (CAR) T-cell immunotherapy has demonstrated remarkable success in treating hematologic neoplasms, the identification of suitable targets remains a major obstacle in translating this approach to solid tumors.
Methods: Peripheral blood T lymphocytes from six healthy donors were used to generate GD2-specific CAR T cells via retroviral transduction.

Acne is a multifactorial dermatological condition driven by Propionibacterium acnes (P. acnes) infection, inflammation, and sebum dysregulation. While essential oils, such as Angelica sinensis (Danggui) essential oil (AEO), exhibit antimicrobial and anti-inflammatory properties, their clinical application is hindered by poor solubility, stability, and skin penetration.

Background: Pollen Typhae (PT), a traditional Chinese medicine herb utilized in diabetes management, exerts anti-inflammatory effects through its flavonoids, yet the active constituents and mechanisms remain unclear.
Methods: PT total flavone (PTF) was extracted from PT and identified the compounds by UHPLC-MS. Network pharmacology and molecular docking were used to predict the underlying targets and anti-inflammatory mechanisms of PTF.

Under physiologic conditions, proximal tubules depend on basolateral fatty acid (FA) uptake for metabolism. In pathophysiologic conditions due to glomerular filtration barrier disruption, albumin-bound FA undergo filtration and proximal tubule reabsorption, which leads to lipotoxicity and tubular atrophy. Apical proximal tubule albumin uptake is accomplished by the megalin/cubilin complex and receptor-mediated endocytosis, whereas apical proximal tubule FA uptake is primarily mediated by apical fatty acid transport protein-2 (FATP2).
