Brief introduction

The ISD map is a network of atopic dermatitis (AD)- and psoriasis (PsO)-specific causal molecular interactions represented as computable diagrams. It is available as a set of interactive diagrams, similar to canonical pathway databases, but focused on AD and PsO mechanisms. The ISD map can be used for data interpretation, hypothesis generation and simulation modelling.

Structure of the ISD map

The map is comprised by three layers: a side-by-side layer that is the entry point for the ISD map and contains the key molecules and cells associated with AD and PsO, the intercellular communication views depicting how AD and PsO-relevant cell types interact, and the intracellular pathways layer illustrating signalling networks within some selected cells.

Applications of the ISD map

To demonstrate how the map can be used, we offer here some applications along with a step-by-step guide to reproduce the analysis:
