The histological examination reveals mainly two subtypes of MC, lymphocytic or collagenous colitis.
There are mainly two subtypes of TRs, TRα and TRβ, expressed from two different genes.
In our current study, we focused on immune cells, mainly three subtypes of T helper cells- Th1, Th17 and Th22 cells and their probable role in CC and CIN.
NSCLC tumors consist mainly of three subtypes: adenocarcinoma (40% of lung cancers), squamous cell carcinoma (25% of lung cancers), and large cell carcinoma (10% of lung cancers).
On the other hand, the group III receptors including four subtypes, such as mGlu4 and mGlu6 to 8, are less understood, mainly due to the paucity of specific ligands for these receptors.
The influenza strains initially used for predicting epitopes mainly belong to five subtypes: H3N2, 124 epitope predicted (ep); H1N1, 68 ep; H5N1, 35 ep; H2N2, 55 ep; and H1N2, 86 ep.
Cell-surface receptors of TGFβ signaling are mainly classified into two subtypes: type I (TGFβRI) and type II (TGFβRII).
Lung cancer is mainly divided into two subtypes, small cell lung cancer (SCLC), which accounts for 10-15% of all cases and non-small cell lung cancer (NSCLC, 85-90%).
Mental clauses construe processes of sensing; they are distinguished grammatically into four subtypes: emotion subtype (2.75 %); perception subtype (2.02 %); cognition subtype (0.89 %); desideration subtype (0.08 %).
Four subtypes are described: well-differentiated or atypical lipomatous tumour (most common subtype), myxoid including round cell, de-differentiated (least common subtype) and pleomorphic [55].
