Insights

Inhibiting immune checkpoint pathways can help fight infections, similar to cancer treatment. Further research is needed to develop safe and effective strategies for patients with infectious diseases.

Area of Science:

  • Immunology
  • Oncology
  • Infectious Diseases

Background:

  • T cell exhaustion and dysfunction impair the immune response against infections and cancer.
  • Blocking inhibitory immune checkpoints has proven effective in treating various cancers.

Purpose of the Study:

  • To review the potential of inhibiting immune checkpoint pathways for controlling or clearing infectious diseases.
  • To highlight the need for further research in translating these strategies for clinical use in infections.

Main Methods:

  • Review of emerging evidence on immune checkpoint inhibition in infectious diseases.
  • Analysis of current research trends and clinical relevance.

Main Results:

  • Immune checkpoint inhibition shows promise in preclinical and some clinical studies for infectious diseases.
  • Significant challenges remain in optimizing safety and efficacy for clinical application.

Conclusions:

  • Inhibiting immune checkpoint pathways is a potential therapeutic strategy for infectious diseases.
  • Development of safe and clinically translatable strategies requires substantial further investigation.

Cells of the Innate Immune Response

The innate immune response is an immediate and non-specific response against pathogens, acting swiftly to prevent the spread of infections. The primary cells involved in this response are phagocytes and natural killer (NK) cells.
Phagocytes
Phagocytes police the peripheral tissues by removing cellular debris and responding to the invasion of foreign substances or pathogens. Many phagocytes attack and remove microorganisms even before lymphocytes detect them. The human body has two general...

The Intrinsic Apoptotic Pathway01:31

The Intrinsic Apoptotic Pathway

Internal cellular stress, such as cellular injury or hypoxia, triggers intrinsic apoptosis. The B-cell lymphoma 2 (Bcl-2) family of proteins are the primary regulators of the intrinsic apoptotic pathway. For example, during DNA damage, checkpoint proteins, such as Ataxia Telangiectasia Mutated (ATM protein) and Checkpoints Factor-2 (Chk2) proteins, are activated. These proteins phosphorylate p53 which further activates pro-apoptotic proteins, such as Bax, Bak, PUMA, and Noxa, and inhibits...

Abnormal Proliferation02:23

Abnormal Proliferation

Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the...

The Extrinsic Apoptotic Pathway01:17

The Extrinsic Apoptotic Pathway

The extrinsic apoptotic pathway is initiated when extracellular death-inducing signals, such as specific cytokines, activate the death receptors expressed on the cell surface. The immune cells involved in this pathway are natural killer cells (NK cells) and cytotoxic T-lymphocytes. NK cells are critical in innate immune response, while cytotoxic T-lymphocytes are associated with adaptive immune response. These cells recognize specific receptors expressed on the altered cells and activate...

Overview of Cell Death01:30

Overview of Cell Death

Cell death is an essential process where the body gets rid of old or damaged cells. Cell proliferation and death need to be balanced, as an imbalance between the two may lead to cancer or autoimmune diseases.
Cell death was observed in the early 19th century, but there was no experimental evidence to prove it. In 1842, Carl Vogt first discovered cell death in a metamorphic toad; however, it was not termed ‘cell death.’ Scientists discovered different cell death pathways only in the...
