mice (B) Immunofluorescence images from eWAT from mice IP or IV injected
with CFSE-labeled CD4 cells. Scale bar = 50 µm. (C) Quantitation of

MHCII deficient mice (MHCIIKO) and wild-type control male mice (WT) were fed
with normal chow diet (ND) or high-fat diet (HFD) for 20 weeks and metabolic
cage studies were conducted. (A) Oxygen consumption (VO2) (B) Carbon
dioxide production (VCO2) (C) body length. Data are means ± SEM.

lymphocyte population, proliferation and Th1 polarization in response to
HFD. (Related to Figure 6)
(A) Gating strategy of Treg. (B) Representative flow cytometry plot of Treg in
spleen and eWAT from ND and HFD for 14 weeks. (C) Quantitation of CD3+
lymphocytes, CD4+, CD8+, Tconv, Treg, proliferating CD4+ and CD8+ T
lymphocytes, and IFNg expression in sorted CD4+ cells in spleen from HFD fed
CON and MMKO. Data are means ± SEM.
Figure S6 (Related to Figure 7)
Figure S6. Depletion of CD11c+ cells improves HFD-induced glucose
intolerance without changes of adiposity. (Related to Figure 7)
PBS or Diphteria Toxin (DT) was injected into CD11c-DTR bone marrow chimeric
mice fed ND or HFD for 8 weeks during the last 2 weeks of HFD feeding. (A)

Movies S1-S2
Movie S1. Dynamic interaction of CD4+ T cells with ATMs in the absence of
antigen. (Related to Figure 1)
CFSE-labeled CD4+ T cells from OT II mice were adoptively transferred to
CD11c-mcherry mice. 2 h post injection of BSA, CFSE-CD4+ T cell (green) and
CD11c-mCherry+ ATMs (red) were imaged in eWAT of an anesthetized mouse
using two-photon microscopy.
Movie S2. Stable interaction of CD4+ T cells with ATMs in the presence of
antigen. (Related to Figure 2)
CFSE-labeled CD4+ T cells from OT II mice were adoptively transferred to
CD11c-mcherry mice. 2 h post injection of OVA, CFSE-CD4+ T cell (green) and
CD11c-mCherry+ ATMs (red) were imaged in eWAT of an anesthetized mouse
using two-photon microscopy
