The task is to decide the Hallmarks of Cancer (HOC) taxonomy of the article based on its abstract. The input is an abstract text. There are 10 topics you will need to decide whether the article is related to. Topics: sustaining proliferative signaling, evading growth suppressors, resisting cell death, enabling replicative immortality, inducing angiogenesis, activating invasion and metastasis, genomic instability and mutation, tumor promoting inflammation, cellular energetics, avoiding immune destruction. The output should be topics from the above 10 topics, that are related to the input article. Please note one article can be related to multiple topics. Output format: provide a semicolon-separated list of relevant topics.

    INPUT: Pam3CSK4 , a synthetic TLR2 ligand , has been shown to expand CD4+ regulatory T cells ( Treg cells ) . Less is known about the function of CD8+ Treg cells than about the function of CD4+ Treg cells generated during allergen-specific immunotherapy ( IT ) . This study investigated whether Dermatophagoides pteronyssinus-specific IT could expand the CD8+CD25+Foxp3+ Treg population and whether Pam3CSK4 could enhance the Treg population . PBMCs were isolated from healthy control subjects and from mite-sensitive asthmatic patients during IT at three specific times : before IT and 6 mo and 1 y after the maximum-tolerated dose . This study was performed without a placebo-controlled group . D. pteronyssinus-specific IT induced a significant increase in CD8+Foxp3+ Treg cells expressing intracellular IL-10 and granzyme B. Costimulation of PBMCs with Pam3CSK4 and D. pteronyssinus 2 expanded the CD8+CD25+Foxp3+ Treg population and inhibited D. pteronyssinus 2-induced IL-4 production . Pam3CSK4-treated CD8+CD25+ Treg cells directly suppressed CD4+ T cell proliferation by cell-contact inhibition . TUNEL revealed that CD8+CD25+ Treg cells , but not CD4+CD25+ Treg cells , directly induced CD4+CD45ROhi+ apoptosis . Our results provide direct evidence that Pam3CSK4 induces an immunomodulatory effect by inducing CD8+ Treg cells ; therefore , it may be a good adjuvant for the treatment of mite allergies .
    OUTPUT:
