◐Partially SupportedThe PD-1/PD-L1 pathway suppresses the immune system by signaling T cells to shut down.◐Partially SupportedCancer cells can adopt a biological behavior similar to backing up in the developmental process, exhibiting surface markers not found in fully mature tissues.◐Partially SupportedNatural killer (NK) cells destroy cells that stop presenting antigens on their surface.◐Partially SupportedCancers can recruit suppressive immune cell types to dampen immune system response.◐Partially Supported

Bookmarking — the dossier-vs-overview split is the right call. Most of the time I want overview; sometimes I want receipts.

The immune system limits immune responses to prevent excessive inflammation and metabolic resource consumption.

◐Partially SupportedCancers can impede immune system recognition and response through genetic mechanisms like the PD-1/PD-L1 pathway.

◐Partially SupportedProto-cancers are eliminated by the immune system, as individuals with compromised immune systems have a higher incidence of cancers.

◐Partially SupportedAll cells in the body present protein fragments (peptides) on their surface via MHC molecules to the immune system.

◐Partially SupportedMutations in genes caused by carcinogens can lead to altered proteins with unique amino acid sequences recognizable by the immune system.

◐Partially SupportedBroadening the use of immunotherapy in cancer requires understanding the specific mechanisms cancers employ to defend themselves.

◐Partially SupportedBlocking the PD-1/PD-L1 interaction has produced greater incremental benefit in cancer treatment than any other single mechanism discovered.

◐Partially SupportedCancer testis antigens are surface markers that the immune system can recognize.

◐Partially SupportedCancer can arise from mutations in genes that disable DNA repair or activate surface receptors and downstream signaling molecules.

◐Partially SupportedUnderstanding the immune system is crucial for comprehending mechanisms of cancer drugs like T-cell therapies and checkpoint inhibitors.

◐Partially SupportedNatural killer (NK) cells can detect and eliminate cells that stop presenting antigens.

◐Partially SupportedThe immune system's role in cancer optimism has grown significantly over the past two decades and is expected to increase further.

◐Partially SupportedThe immune system identifies cancer cells by detecting fundamental differences from normal cells.
