T Cell Activation and Clonal Selection01:22

T Cell Activation and Clonal Selection

17.3K
T cells are integral to our adaptive immune system, recognizing and effectively responding to foreign antigens. T cell activation and clonal selection are pivotal in orchestrating this immune response. This article elucidates these mechanisms, detailing the roles of cluster of differentiation (CD) markers, major histocompatibility complex (MHC) molecules, costimulatory signals, and the process of clonal selection.
Naive T cells that have not yet encountered an antigen express two primary CD...

Cells of the Innate Immune Response

10.4K
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...

Cytotoxic T Cells-mediated Immune Response01:27

Cytotoxic T Cells-mediated Immune Response

8.2K
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...

Immune Response Against Viral Pathogens01:29

Immune Response Against Viral Pathogens

2.5K
The immune system's response to viral infections is a complex and coordinated process involving natural killer (NK) cells, T cell-mediated responses, and antibody-mediated responses.
NK Cells
NK cells are a crucial part of our innate immune system, acting as the first line of defense against viral infections. These cells can recognize and kill infected cells without prior exposure to the virus, effectively slowing down the spread of infection. Additionally, NK cells produce proinflammatory...

Diversity of Antigen Receptors01:28

Diversity of Antigen Receptors

2.1K
Antigen receptors are essential components of the immune system crucial in defending the body against foreign invaders. These receptors are present on the surface of B and T cells, enabling them to recognize antigens and mount an appropriate immune response.
Before encountering any antigen, lymphocytes express these receptors. On B cells, the antigen receptor is a membrane-bound antibody molecule called BCR; on T cells, it is a T cell receptor or TCR. B and T cell receptors are composed of two...

Cells of the Adaptive Immune Response01:23

Cells of the Adaptive Immune Response

10.0K
The T and B lymphocytes of the adaptive immune system develop from common lymphoid progenitor cells in the bone marrow. These progenitors give rise to precursors that eventually develop into both T and B lymphocytes. As these precursors mature, they gain the ability to detect and respond to foreign antigens in the body, a process known as immunocompetence. Additionally, these precursors acquire self-tolerance, a process that ensures they do not react to self-antigens. This intricate system...

Area of Science:

  • Immunology
  • Cellular Biology
  • Innate Immunity

Background:

  • Natural killer (NK) cells are innate lymphocytes crucial for early immune responses.
  • NK cells possess both innate effector functions and adaptive capabilities, including memory formation.
  • Their function is regulated by a 'three-signal' framework involving receptor engagement, co-stimulation, and cytokines.

Purpose of the Study:

  • To review emerging molecular pathways for modulating NK cell signaling.
  • To explore the reprogramming of NK cells for therapeutic applications.

Main Methods:

  • This review synthesizes current knowledge on NK cell signaling pathways.
  • Focuses on strategies targeting the three-signal framework (receptor engagement, co-stimulation, cytokines).

Main Results:

  • NK cells demonstrate plasticity, bridging innate and adaptive immunity.
  • Modulating the three signals offers potential for enhancing NK cell-based therapies.

Conclusions:

  • Understanding and manipulating NK cell signaling is key to unlocking their full therapeutic potential.
  • Reprogramming NK cells via their three-signal network represents a promising avenue in immunotherapy.
