The summary of hub genes.

Gene symbolFull nameFunction

CCL5C-C motif chemokine ligand 5This gene is one of several chemokine genes clustered on the q-arm of chromosome 17. Chemokines form a superfamily of secreted proteins involved in immunoregulatory and inflammatory processes.
CCR7C-C motif chemokine receptor 7Receptor for the MIP-3-beta chemokine. Probable mediator of EBV effects on B-lymphocytes or of normal lymphocyte functions.
CD2CD2 moleculeThe protein encoded by this gene is a surface antigen found on all peripheral blood T-cells. The encoded protein interacts with LFA3 (CD58) on antigen presenting cells to optimize immune recognition.
CD27CD27 moleculeThe protein encoded by this gene is a member of the TNF-receptor superfamily.
CD274CD274 moleculeThis gene encodes an immune inhibitory receptor ligand that is expressed by hematopoietic and non-hematopoietic cells, such as T cells and B cells and various types of tumor cells.
CD3DCD3d moleculeThe protein encoded by this gene is part of the T-cell receptor/CD3 complex (TCR/CD3 complex) and is involved in T-cell development and signal transduction.
GNLYGranulysinThe product of this gene is a member of the saposin-like protein (SAPLIP) family and is located in the cytotoxic granules of T cells, which are released upon antigen stimulation.
GZMAGranzyme AGZMA is a T cell- and natural killer cell-specific serine protease that may function as a common component necessary for lysis of target cells by cytotoxic T lymphocytes and natural killer cells.
GZMHGranzyme HThis protein is reported to be constitutively expressed in the NK (natural killer) cells of the immune system and may play a role in the cytotoxic arm of the innate immune response by inducing target cell death and by directly cleaving substrates in pathogen-infected cells.
GZMKGranzyme KThis gene product is a member of a group of related serine proteases from the cytoplasmic granules of cytotoxic lymphocytes.
IL2RBInterleukin 2 receptor subunit betaReceptor for interleukin-2. This beta subunit is involved in receptor mediated endocytosis and transduces the mitogenic signals of IL2. Probably in association with IL15RA, involved in the stimulation of neutrophil phagocytosis by IL15.
IL7RInterleukin 7 receptorThe protein encoded by this gene is a receptor for interleukin 7 (IL7).
ITKIL2 inducible T cell kinaseThis gene encodes an intracellular tyrosine kinase expressed in T-cells. The protein contains both SH2 and SH3 domains which are often found in intracellular kinases. It is thought to play a role in T-cell proliferation and differentiation.
KLRB1Killer cell lectin like receptor B1Plays an inhibitory role on natural killer (NK) cells cytotoxicity.
PRF1Perforin 1This gene encodes a protein with structural similarities to complement component C9 that is important in immunity.
