CellChat：细胞间相互作用分析利器
分享是一种态度
前言
我们知道，细胞间信息传递方式一个是细胞表面配受体的相互作用，另一个通过细胞产生的可溶性小分子，即细胞因子。在单细胞数据分析中下游，有时候我们想看某几种细胞类型之间的相互作用，就有人推荐我们做一个配受体分析。那什么是配受体？我们在文章Cell-Cell Interaction Database|| 单细胞配受体库你还在文章的附录里找吗？中提到配受体其实是细胞的特定蛋白，蛋白追溯到基因表达上就是基因对。

今天，我们就用CellChat来分析一下我们的PBMC数据，看看配受体分析的一般流程。
除了从任何给定的scRNA-seq数据推断细胞间通信外，CellChat还提供了进一步的数据探索、分析和可视化功能。
它能够分析细胞与细胞间的通讯，以获得细胞发展轨迹上的连续状态。
该方法结合社会网络分析、模式识别和多种学习方法，可以定量地描述和比较推断出的细胞间通信网络。
它提供了一个易于使用的工具来提取和可视化推断网络信息。例如，它可以随时预测所有细胞群的主要信号输入和输出，以及这些细胞群和信号如何协调在一起实现功能。
它提供了几个可视化输出，以方便用户引导的直观数据解释。

CellChat需要两个输入:
一个是细胞的基因表达数据，
另一个是细胞标签(即细胞标签)。
对于基因表达数据矩阵，基因应该在带有行名的行中，cell应该在带有名称的列中。CellChat分析的输入是均一化的数据(Seurat@assay$RNA@data)。如果用户提供counts数据，可以用normalizeData函数来均一化。对于细胞的信息，需要一个带有rownames的数据格式作为CellChat的输入。
这两个文件在我们熟悉的Seurat对象中是很容易找到的，一个是均一化之后的数据，一个是细胞类型在metadata中。那么就让我们开始chat之旅吧。
数据配置
首先，我们加载包和引入实例数据。
1library(CellChat)
2library(ggplot2)
3library(ggalluvial)
4library(svglite)
5library(Seurat)
6library(SeuratData)
7options(stringsAsFactors = FALSE)
我们用Seurat给出的pbmc3k.final数据集，大部分的计算已经存在其对象中了：
1pbmc3k.final

413714 features across 2638 samples within 1 assay

8 pbmc3k.final@commands$FindClusters # 你也看一看作者的其他命令，Seurat是记录其分析过程的。

18random.seed : 0
19group.singletons : TRUE

按照我们刚才说的，我们在Seurat对象中提出CellChat需要的数据：
1data.input <- pbmc3k.final@assays$RNA@data
2identity = data.frame(group =pbmc3k.final$seurat_annotations , row.names = names(pbmc3k.final$seurat_annotations)) # create a dataframe consisting of the cell labels
3unique(identity$group) # check the cell labels

S4 类学会了吗？
在学习单细胞数据分析工具的时候，在知道了要干嘛之后，第二步就是看数据格式，俗称：单细胞数据格式。我们在听说你的单细胞对象需要一个思维导图？，曾给出一个简单的可视化数据结构的方法：导图。
1library(mindr)
2(out <- capture.output(str(cellchat)))
3out2 <- paste(out, collapse="\n")
4mm(gsub("\\.\\.@","# ",gsub("\\.\\. ","#",out2)),type ="text")
当然，我们可以用str来看，就是有点冗长：
1> str(cellchat)

我们把metadata信息加到CellChat对象中，这个写法跟Seurat很像啊。
1cellchat <- addMeta(cellchat, meta = identity, meta.name = "labels")
2cellchat <- setIdent(cellchat, ident.use = "labels") # set "labels" as default cell identity

导入配受体数据库
CellChat提供了人和小鼠的配受体数据库，分别可以用CellChatDB.human,CellChatDB.mouse来导入。来看一下这个数据库的结构吧。
1CellChatDB <- CellChatDB.human
2(out3 <- capture.output(str(CellChatDB)))
3out4 <- paste(out3, collapse="\n")
4mm(gsub("\\$","# ",gsub("\\.\\. ","#",out4)),type ="text")

其实是记录了许多许多受配体相关的通路信息，不像有的配受体库只有一个基因对。这样，我们就可以更加扎实地把脚落到pathway上面了。在CellChat中，我们还可以先择特定的信息描述细胞间的相互作者，这个可以理解为从特定的侧面来刻画细胞间相互作用,比用一个大的配体库又精细了许多呢。
1CellChatDB.use <- subsetDB(CellChatDB, search = "Secreted Signaling") # use Secreted Signaling for cell-cell communication analysis
2cellchat@DB <- CellChatDB.use # set the used database in the object
有哪些可以选择的侧面呢？
1> unique(CellChatDB$interaction$annotation)
2[1] "Secreted Signaling" "ECM-Receptor" "Cell-Cell Contact"
预处理
对表达数据进行预处理，用于细胞间的通信分析。首先在一个细胞组中识别过表达的配体或受体，然后将基因表达数据投射到蛋白-蛋白相互作用(PPI)网络上。如果配体或受体过表达，则识别过表达配体和受体之间的相互作用。
1cellchat <- subsetData(cellchat) # subset the expression data of signaling genes for saving computation cost
2future::plan("multiprocess", workers = 4) # do parallel 这里似乎有一些bug，在Linux上居然不行。de了它。
3cellchat <- identifyOverExpressedGenes(cellchat)
4 cellchat <- identifyOverExpressedInteractions(cellchat)
5cellchat <- projectData(cellchat, PPI.human)
相互作用推断
然后，我们通过为每个相互作用分配一个概率值并进行置换检验来推断生物意义上的细胞-细胞通信。
1# cellchat <- computeCommunProb(cellchat) 注意这个函数如果你可以用就用，这个是作者的。
2mycomputeCommunProb <-edit(computeCommunProb) # computeCommunProb内部似乎有一些bug，同一套数据在window10上没事，到了Linux上有报错。发现是computeExpr_antagonist这个函数有问题，(matrix(1, nrow = 1, ncol = length((group))))，中应为(matrix(1, nrow = 1, ncol = length(unique(group))))？ 不然矩阵返回的不对。de了它。
3environment(mycomputeCommunProb) <- environment(computeCommunProb)
4cellchat <- mycomputeCommunProb(cellchat) # 这儿是我de过的。
推测细胞间在信号通路水平上的通讯。我们还通过计算与每个信号通路相关的所有配体-受体相互作用的通信概率来推断信号通路水平上的通信概率。
注:推测的每个配体-受体对的细胞间通信网络和每个信号通路分别存储在“net”和“netP”槽中。
我们可以通过计算链路的数量或汇总通信概率来计算细胞间的聚合通信网络。
1cellchat <- computeCommunProbPathway(cellchat)
2cellchat <- aggregateNet(cellchat)
让我们看看这结果。

在推断细胞-细胞通信网络的基础上，CellChat为进一步的探索、分析和可视化提供了各种功能。
通过结合社会网络分析、模式识别和多种学习方法的综合方法，t可以定量地描述和比较推断出的细胞-细胞通信网络。
它提供了一个易于使用的工具来提取和可视化推断网络的高阶信息。例如，它可以随时预测所有细胞群的主要信号输入和输出，以及这些细胞群和信号如何协调在一起实现功能。
你可以使用层次图或圈图可视化每个信号通路。如果使用层次图可视化通信网络，请定义vertex.receiver，它是一个数字向量，给出作为第一个层次结构图中的目标的细胞组的索引。我们可以使用netVisual_aggregate来可视化信号路径的推断通信网络，并使用netVisual_individual来可视化与该信号路径相关的单个L-R对的通信网络。
在层次图中，实体圆和空心圆分别表示源和目标。圆的大小与每个细胞组的细胞数成比例。边缘颜色与信源一致。线越粗，信号越强。这里我们展示了一个MIF信号网络的例子。所有显示重要通信的信令路径都可以通过cellchat@netP$pathways访问。

经典的配受体圈图：
1mynetVisual_aggregate(cellchat, signaling = c("MIF"), layout = "circle", vertex.size = groupSize,pt.title=20,vertex.label.cex = 1.7)
计算和可视化每个配体-受体对整个信号通路的贡献度。
1netAnalysis_contribution(cellchat, signaling = pathways.show)
识别细胞群的信号转导作用，通过计算每个细胞群的网络中心性指标，CellChat允许随时识别细胞间通信网络中的主要发送者、接收者、调解者和影响者。
1cellchat <- netAnalysis_signalingRole(cellchat, slot.name = "netP") # the slot 'netP' means the inferred intercellular communication network of signaling pathways
1netVisual_signalingRole(cellchat, signaling = pathways.show, width = 12, height = 2.5, font.size = 10)
识别特定细胞群的全局通信模式和主要信号。除了探索单个通路的详细通讯外，一个重要的问题是多个细胞群和信号通路如何协调运作。CellChat采用模式识别方法来识别全局通信模式以及每个小群的关键信号。
识别分泌细胞外向交流模式。随着模式数量的增加，可能会出现冗余的模式，使得解释通信模式变得困难。我们选择了5种模式作为默认模式。一般来说，当模式的数量大于2时就可以认为具有生物学意义。
1nPatterns = 5
2# 同样在这里遇到了bug，难道说是我没有安装好吗，de了它。
3# cellchat <- myidentifyCommunicationPatterns(cellchat, pattern = "outgoing", k = nPatterns)

1# Visualize the communication pattern using river plot
2netAnalysis_river(cellchat, pattern = "outgoing")
1# Visualize the communication pattern using dot plot
2netAnalysis_dot(cellchat, pattern = "outgoing")
识别目标细胞的传入(incoming)通信模式。
1netAnalysis_river(cellchat, pattern = "incoming")
1netAnalysis_dot(cellchat, pattern = "incoming")
作为结尾有大量的空间，我们得以先看看cellchat配受体推断的结构是如何的。
