Non-lymphoid tissue CD11b+ cDC are heterogeneous.
(a) PCA of the top 15% most variable transcripts
expressed by lymphoid tissue CD8+ cDC,
CD8− cDC, non-lymphoid tissue CD103+
cDC, non-lymphoid tissue CD11b+ cDC, epidermal LC and MF.
Population means are shown. Population color labels displayed next to heatmap
column labels of Fig 4c. (b) Graph show percentages of core cDC
transcripts (identified in Fig. 2) that are
up-regulated (FC≥2) in CD11b+ cDC subsets and red
pulp MF. (c) Heat map indicates the relative expression of cDC and
MF transcripts in each cDC population. Red represents high relative expression,
while blue represents low relative expression. (d) Small intestine
single cell suspensions were analyzed by flow cytometry for core cDC genes. Dot
plot shows the expression of CD103 and CD11b on
DAPI−CD45+CD11c+MHCII+
lamina propria cDC. Histograms show the expression of Flt3, CD26, c-Kit, and
BTLA among CD103+CD11b− cells,
CD103+CD11b+ F4/80−
cells and CD103+CD11b+
F4/80+ cells. Data shown are representative of three
different experiments. MLN: mesenteric LN; SDLN: skin draining LN; SI:
small intestine. LC: Langerhans cells.. *Replicates n
