Modulation of Toll-Like Receptor Activity by Leukocyte Ig-Like Receptors and Their Effects during Bacterial Infection

Table 1

Expression profile of TLR and LILR on different APC subsets: this table depicts the known expression levels of TLRs and LILR on subsets of APCs. $+$ denotes high expression, $-/+$ denotes weak expression, and $-$ is no expression. ? is used where expression levels are yet to be determined [5–14].
