Although nearly a century has passed since histiocytic disorders were recognized,their pathophysiology has started to be elucidated with the application of molecular analyses.

Costimulatory interaction (i.e., second signal) is between CD80(B7.1)/CD86(B7.2) on the dendritic cell, and CD28 on the T cells.

For example, the entity now referred to as Langerhans cell histiocytosis (LCH) was initially divided into eosinophilic granuloma, Hand-Schüller-Christian disease, and Abt-Letterer-Siwe disease, depending on the sites and severity.

Later, these were found to be manifestations of a single entity and were unified under the term histiocytosis X.

Dendritic cells can produce several cytokines, including IL-12, which is critical for the development of T Ligation of CD40 on dendritic cells triggers the production of large amounts of IL-12, which enhances T-cell stimulatory capacity.

This observation suggests that feedback to dendritic cells results in signals that are critical for induction of immune responses.

Immature dendritic cells express receptors that mediate endocytosis, including C-type lectin receptors, such as the macrophage mannose receptor and DEC205, FC-gamma, and FC-epsilon receptors.

Microbial components, as well as IL-1, GM-CSF, and TNF-alpha, have an important role in cellular response Mature dendritic cells possess numerous fine processes (veils, dendrites) and have considerable mobility.Tissue engineering tools enable three-dimensionality based on the design of biomaterials and scaffolds that re-create the geometry, chemistry, function and signalling milieu of the native tumour microenvironment.Three-dimensional (3D) microenvironments, including cell-derived matrices, biomaterial-based cell culture models and integrated co-cultures with engineered stromal components, are powerful tools to study dynamic processes like proteolytic functions associated with cancer progression, metastasis and resistance to therapeutics.These cells, rich in MHC classes I and II, have abundant molecules for T-cell binding and co-stimulation, which involves CD40, CD54, CD58, CD80/B7-1, and CD86/B7-1.Mature dendritic cells express high levels of IL-12.Such a description excludes diseases in which infiltration of these cells occurs in response to a primary pathology.
