Figure Lengend Snippet: Immunomodulatory effects of the bioengineered LEVs Tet−PKM2 @TA in terms of their ability to modulate macrophage polarization in vitro . The macrophages were treated with 100 ng/mL LPS for 24 h and then treated with PBS (Control), 100 μg/mL LEVs PKM2 , LEVs Tet−PKM2 , or LEVs Tet−PKM2 @TA for another 24 h. ( A ) The relative mRNA expression levels of M1 polarization-related genes ( IL-6 and IL-1β ) and M2 polarization-related genes ( IL-4 and Arg-1 ) in the Control, LEVs PKM2 , LEVs Tet−PKM2 , and LEVs Tet−PKM2 @TA groups (qRT‒PCR) ( n = 3). ( B ) Concentrations of M1-related cytokines (IL-6 and TNF-α) and M2-related cytokines (IL-4 and IL-10) in the supernatants of the Control, LEVs PKM2 , LEVs Tet−PKM2 , and LEVs Tet−PKM2 @TA groups (ELISA) ( n = 3). ( C ) Representative immunofluorescence images and quantification of the expression levels of M1-related proteins (iNOS and CCR7) and M2-related proteins (CD163, CD206, and Arg-1) in the Control, LEVs PKM2 , LEVs Tet−PKM2 , and LEVs Tet−PKM2 @TA groups ( n = 3). The data are expressed as the mean ± SEM. Statistical analysis was performed with one-way ANOVA ( A , B , and C ). ∗ p < 0.05, ∗∗ p < 0.01, and ∗∗∗ p < 0.001 indicate significant differences between the indicated columns.

Article Snippet: Kits were sourced as follows: TNF-α, IL-4, and IL-10 from Fankew (Shanghai Kexing Trading Co., Ltd., China) and IL-6 from Proteintech.

Figure Lengend Snippet: Regulation of MN patches on the inflammation, JAK1 and Nrf2/HO-1 pathways in AD mice. ( a-c ) Levels of IL-1β, IL-4, and IL-13 in the dorsal skin. ( d, e ) Levels of TSLP and IgE in the serum. ( f ) Protein expression of JAK1 in the dorsal skin. ( g ) Quantitative analysis of JAK1 protein levels from (f). ( h ) 8-OHdG levels in the dorsal skin. ( i ) Fluorescent immunostaining of Nrf2, with the merged image showing DAPI staining (red: Nrf2, blue: DAPI). ( j ) Quantitative analysis of Nrf2 protein expression from (i). ( k ) Fluorescent immunostaining of HO-1, along with the merged image showing DAPI staining (red: HO-1, blue: DAPI). ( l ) Quantitative analysis of HO-1 protein expression from (k). Data are presented as mean ± SD (n = 6). Bars sharing the same letter are not significantly different, whereas those with different letters are statistically significant (p < 0.05).

Article Snippet: The 8-OHdG ELISA Kit was purchased from Youersheng Technology Co., Ltd (Wuhan, China), and the mouse IL-13 uncoated ELISA kit was purchased from Lianke Biotechnology Co., Ltd (Hangzhou, China).
