Insights

Gene associated with retinoid-interferon-β-induced mortality (GRIM)-19 is crucial for cell death and growth control. This protein also plays a role in the innate immune response, despite viruses hijacking it for survival.

Area of Science:

  • Molecular Biology
  • Immunology
  • Cell Biology

Background:

  • Gene associated with retinoid-interferon-β-induced mortality (GRIM)-19 was identified as a key regulator of cell death.
  • GRIM-19's role in cell death is induced by Interferon-β and Retinoic acid.
  • GRIM-19's dual role in promoting cell death and enabling cell growth is recognized.

Purpose of the Study:

  • To review the multifaceted roles of GRIM-19.
  • To discuss GRIM-19's involvement in growth control.
  • To explore GRIM-19's function in innate immune responses.

Main Methods:

  • Literature review of GRIM-19 functions.
  • Analysis of GRIM-19's regulatory mechanisms.
  • Synthesis of current research on GRIM-19.

Main Results:

  • GRIM-19 overexpression induces cell death; suppression promotes cell growth.
  • GRIM-19 targets multiple proteins and pathways for growth control.
  • Viruses utilize GRIM-19 for their replication, while bacteria can induce its expression.

Conclusions:

  • GRIM-19 is essential for cellular processes and innate immunity.
  • Understanding GRIM-19's complex roles is critical for therapeutic strategies.
  • Further research is needed to fully elucidate GRIM-19's functions in health and disease.

Cell-mediated Immune Responses

Overview
Cytotoxic T Cells-mediated Immune Response01:27

Cytotoxic T Cells-mediated Immune Response

Cytotoxic T cells are a vital component of the immune system. They have the remarkable ability to identify and target antigens on infected or abnormal cells. These antigens often originate from intracellular pathogens such as viruses or abnormal proteins cancer cells produce.
Immunological surveillance is the ability of immune cells to monitor and eliminate infected cells with intracellular pathogens, neoplastically transformed cells, and cells with non-self antigens. Cytotoxic T cells and NK...
Tumor Immunotherapy01:27

Tumor Immunotherapy

Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.
Cells of the Innate Immune Response01:28

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...
Inflammatory Response01:28

Inflammatory Response

An inflammatory response is a localized, nonspecific immune reaction that occurs when a tissue is injured. It is characterized by redness, swelling, heat, and pain, which are commonly called the cardinal signs and symptoms of inflammation. Inflammation can sometimes result in a loss of function.
Inflammation can be triggered by various stimuli, such as impact, abrasion, chemical irritation, infections, and extreme hot or cold temperatures. These can damage cells and connective tissue fibers,...
TGF - β Signaling Pathway01:16

TGF - β Signaling Pathway

The TGF-β signaling pathway regulates cell growth, differentiation, adhesion, motility, and development. TGF-β ligands that induce TGF-β signaling are synthesized in their latent form. Several proteases or cell surface receptors such as integrins act upon the latent form, releasing the active ligand. There are three types of mammalian TGF-βs: (TGF-β1, TGF-β2, and TGF-β3) that bind as homodimers or heterodimers to TGF-β receptors. The TGF-β receptors are of three kinds RI, RII, and RIII. The RI...
