Intratumor Immunotherapy Kills Injected and Distant Tumors

Share

Cancerous tumors must evade immune destruction to survive. They can achieve this by preventing the immune cells from gaining access to the tumor (“immune cold”) or by tipping the balance of immunoactivating and immunosuppressing signals toward immunosuppression. Immunosuppression means that, even if the immune cells penetrate the tumor, they cannot kill the cancer. The cytotoxicity … Read moreIntratumor Immunotherapy Kills Injected and Distant Tumors

Engineering the Immune System to Treat Diabetes

Type_1_diabetes
Share

Some diseases arise because the immune system reacts with normal, healthy cells in the body. In other diseases, lack of an effective immune response contributes to the disease. Cancer cells escape attack by the immune system, in part, by producing a lot of the protein PD-L1 (Gough, 24 May 2017). PD-L1 binds and activates the … Read moreEngineering the Immune System to Treat Diabetes

Targeting Pyroglutamate Aβ in Alzheimer’s Disease

Amyloid-beta_plaque
Share

Amyloid-beta (Aβ) is a collection of peptide fragments derived from cleavage of amyloid precursor protein (APP). Some of these fragments are toxic to neurons and aggregate forming oligomers and fibrils. These clusters of Aβ form plaques that accumulate in the brains of people with dementia due to Alzheimer’s disease (Figure 1). Preventing the accumulation of … Read moreTargeting Pyroglutamate Aβ in Alzheimer’s Disease

Natural Killer Cells in Cancer Immunotherapy

Share

T cells of the adaptive immune system are not the only cytotoxic cells in the immune system. Natural killer cells (NK cells) are a cytotoxic white blood cell (lymphocyte) of the innate immune system. Clinical trials with NK cells use these as cell-based biologic therapies: The NK cells are the therapy. New research suggests that … Read moreNatural Killer Cells in Cancer Immunotherapy

A main goal of current research and clinical trials is to expand the number of patients that benefit from immune checkpoint inhibitors. Thus, it is perhaps not surprising that combination therapies are the future for these immunotherapies in treating cancer. There are many clinical trials that combine an immunotherapy with conventional chemotherapy (drugs that kill … Read moreMaking Immune “Cold” Tumors Hot
