Figure Lengend Snippet: Characterization, cytotoxicity, uptake, and drug release of biomimetic liposomes. (A, B) Mean diameter (A) and Zeta potential (B) of PLip ( n = 3). (C) The representative Cryo-EM image depicted PLip laden with gambogic acid. Scale bar = 100 nm. (D) CCK-8 assay to evaluate the viability of 4T1 cells after various treatments ( n = 3). (E, F) Representative flow cytometry plots depicting apoptosis in tumor cells following various treatments (F), along with a corresponding statistical graph of late apoptosis (E) ( n = 3). (G, H) Observations of cellular uptake of DiD-labeled liposomes under various treatments using fluorescence confocal microscopy (G, scale bar = 20 μm), and flow cytometric quantification (H) ( n = 3). (I) Alterations of CD44 protein expression in tumor cells following HIFU treatment ( n = 3). (J) Comparison of PLip’s drug release profile in high H 2 O 2 conditions versus an H 2 O 2 -free environment ( n = 3). (K, L) Intracellular (K) and extracellular (L) H 2 O 2 levels following various treatments ( n = 3). Data are presented as mean ± SD. Statistical significance was analyzed by one-way ANOVA with a Tukey post hoc test. ∗ P < 0.05, ∗∗ P < 0.01, ∗∗∗ P < 0.001, ∗∗∗∗ P < 0.0001 vs. indicated; ns, no significance.

Article Snippet: Subsequently, flow cytometric analysis was performed on the cells using FlowJo v.7.6.5 (Tree Star, Inc., Ashland, USA).

Article Title: Validation of LILR antibody specificities and development of LILRA3-specific antibodies

doi: 10.3389/fimmu.2026.1729905

Figure Lengend Snippet: Flow cytometric analysis of antibody reactivity against LILR-expressing K562 cells. (A) Expression of individual LILRs on transfected K562 cells was confirmed by flow cytometry using the following antibodies: LILRB1, clone GHI/75; LILRB2, clone 42D1; LILRB3, clone MKT5.1; LILRB4, clone ZM4.1; LILRB5, clone 395239; LILRA1, clone 586326; LILRA2, clone 600007; LILRA3, rabbit polyclonal antibody; LILRA4, clone 17G10.2; LILRA5, clone 711828; LILRA6, clone 921330. (B) Representative examples of cross-reactivity (anti-LILRA1 antibody clone 586326), specific reactivity (anti-LILRA2 antibody clone 600007), and weak reactivity (anti-LILRA3 antibody clone 2E9). Blue histograms represent parental K562 cells; red histograms represent LILR-expressing cells.

Article Snippet: Flow cytometric analysis was conducted using the MACSQuant Analyzer 10 (Miltenyi Biotec), and data were analyzed using FlowJo software (BD Biosciences).
