These genes are involved in immune response (CD97, FYB, CXCL1, IKBKE, and CCR1), inflammatory response (CD97, CXCL1, C3AR1, CCR1, and LYZ), homeostasis (C3AR1, CCR1, PLN, CCL19, and PPT1), and other processes (JAK/STAT, SOCS, c-IAP1, c-IAP2, XIAP, PI3K/Akt/mTOR, SAPK/ MAPK, and IL-20-induced TNF-[alpha], IL-1[beta], MMP-1, and MMP-13) [44,46].
These genes are Akt1, C3ar1, Ccl19, Ccr1, Cd97, Cxcl1, Fyb, Ifi202b, Ifi203, Ifi204, Ifi205, Ikbke, Lyz1, Map3k13, Mapk10, Mapk10, Mapk13, Pln, Ppt1, Socs1, and Xiap.
Stem cells derived from human ACL tissue have been shown to express the MSC markers CD13, CD29, CD44, CD49c, CD73, CD90, CD97
, CD105, CD146, CD166, SSEA-4, STRO-1, and HLA A, B, C, as well as the pluripotency markers Oct4, Nanog, and Sox2, and demonstrate negative expression of CD34 and CD45 [20-22,25].
We found that proteins such as CXCL5, CCR7, CD55, and CD97
were associated with the immune response.
Importantly, analysis of genes associated with proliferation, differentiation and cell cycle indicated that CD16-positive monocytes represented later stage of differentiation (assessed by substantial expression of broad spectrum of markers characteristic for dendritic cells and macrophages: SIGLEC10, CD43, RARA and CD97
, CD115, C3AR1 respectively) in contrast to CD16-negative monocytes demonstrating high levels of genes coding myeloid (CD1d, CD14, CD93, MNDA) and granulocyte markers (CD114, FPR1) [6,8].
The impact of expressions of CD97
and its ligand CD55 at the invasion front on prognosis of rectal adenocarcinoma.
This suggests that complement-independent effects of DAF1 are the major contributors to tolerance induction via the interaction of DAF (CD55) with its natural ligand, CD97. CD97 is a member of the epidermal growth factor-like, seven span transmembrane (EGF-TM7) family of proteins, is expressed on macrophages, granulocytes, dendritic cells, and smooth muscle cells, and is rapidly upregulated on activated T- and B-cells [106, 107].
Structural studies of a model of the CD55-CD97 complex reveal that the sites of interaction of CD97 and complement components occur on opposite faces of CD55 arguing that CD55 can bind to CD97 and complement independently .
In 1997, the test was planted at four environments: Beeville (BE97), Corpus Christi (CC97), and College Station, TX, (under the same environments used in 1996, CW97, and CD97).

They propose a hypothesis to explain how DAF expression may impact T cell differentiation via interaction with CD97
leading to T regulatory cells, increased production of IL-10, and immune tolerance.
