Therefore, several investigators have employed a cross-subclass approach to reduce effector function.
In a further refinement of the cross-subclass approach, An et al. generated an IgG2 variant with point mutations from IgG4 (i.e., H268Q/V309L/A330S/P331S).
Also, although ranking individuals on the basis of exposure levels rather than modeling serum pollutant levels directly allowed us to compare results between individual pollutants and pollutant subclasses, this approach limits comparisons with other study populations.
A special subclass of such approaches are inference methods based on estimates of mutual information (MI) values [ 23, 29, 30].
In the context of this work, this process can be realized through a hibridization-based or sequencing-based approach (subclasses hybridization-based gene expression measurement and sequencing-based gene expression measurement).
This is done by defining ontology classes and arranging them in a hierarchy super class and subclass using top-down approach [18, 19].
For example, Di Cataldo et al. [31] propose a classification approach based on subclass discriminant analysis (SDA) using the integration of morphological, global, and local texture features.
This approach identified molecular subclasses of HCC, S1, S2 and S3 (Hoshida et al, 2009), where the subclass S1 was characterised by the activation of TGF- β and WNT pathways, EMT-like phenotype and more disseminative clinical phenotype, evidenced as more frequent early tumour recurrence.
Market-based approaches are a subclass of voluntary solutions that add price incentives to the other incentives to cooperate.
Recent reports detailing the expression profiles of primary breast cancer have pointed to the utility of this approach in defining subclasses with distinct molecular configurations and clinical behaviour.
This review outlines the major structural properties that vary across subclasses, how these properties affect functional immunity, and discusses the various approaches used to study subclass responses to infectious diseases.
