The authors have advised Figure 5A on page 1511 is incorrect. Due to an error at the time of figure assembly day 21 Au@PP/poly(I:C)+TMZ and day 28 Au@PP/poly(I:C)+TMZ in the HE 200× row were duplicated. The correct Figure 5 is shown below.

Intranasal Au@PP/poly(I:C) combined with TMZ improves T-cell infiltration and PD-L1 expression in intracranial glioma. (A, C) Representative images of H&E and immunohistochemical staining for CD3, CD8a and PD-L1 in GL261 glioma. The tumor tissue was collected on day 13, day 21 and day 28 after cell inoculating. The images are magnified 25×, 200× and 400× (the scale bars within the photomicrographs are 1000, 100 and 50 microns in length). The red arrows show the positive cells. (B, D) The IHC membrane staining intensity of each cell in a fixed field is determined as 0, 1+, 2+, or 3+, and the IHC score was assigned using the following formula: [1 × (% cells 1+) + 2 × (% cells 2+) + 3 × (% cells 3+)]. We took 3 pictures with 200× magnification per cut section of the brain tumors and counterstained cells from each picture and calculated an average from the three. The results at least include 6 mice per each group. Mean±SEM, n=6–9 in each group. ns: no significant difference, *p<0.05, ***p<0.001 and ****p<0.0001.
The authors apologize for this error and advise it does not affect the results of the paper.
