Annual Review of Immunology
|January 10, 2012
Summary
Innate lymphoid cells (ILCs) are crucial immune cells that rapidly defend against microbes. This review covers their development, functions, and roles in diseases like allergies.
Area of Science:
- Immunology
- Cell Biology
Background:
- Innate lymphoid cells (ILCs) are immune cells lacking antigen receptors but producing effector cytokines similar to T helper cells.
- ILCs play vital roles in lymphoid organogenesis, tissue repair, immunity at barrier surfaces, and inflammation.
- Their rapid response to microbial threats highlights their importance in first-line immune defense.
Purpose of the Study:
- To review current data on the developmental requirements of ILCs.
- To explore the lineage relationships and effector functions of ILC families.
- To discuss the involvement of ILCs in immune-mediated inflammatory and infectious diseases, including allergies.
Main Methods:
- Review of existing scientific literature and data on ILCs.
- Analysis of developmental pathways and lineage relationships.
- Examination of effector cytokine production and functional roles.
Main Results:
- ILCs are key players in mucosal immunity and inflammation, particularly Rorγt-expressing ILCs.
- Type 2 ILCs are crucial for immunity against helminths.
- ILCs contribute to both protective immunity and the pathology of various diseases.
Conclusions:
- ILCs are essential components of the innate immune system with diverse functions.
- Understanding ILCs is critical for developing strategies against inflammatory and infectious diseases.
- Further research into ILCs promises insights into allergy and immune-mediated conditions.

01:18Lymphoid Cells and Tissues
Lymphoid cells and tissues are integral to the immune system, which is crucial in maintaining our body's defense against harmful pathogens. They form the building blocks of lymphoid organs, which include the spleen, thymus, and lymph nodes.
Lymphoid cells consist of various types of immune system cells. These include B and T lymphocytes, which are responsible for producing antibodies and killing infected cells, respectively. Dendritic cells act as messengers between the innate and adaptive...

01:23Cells of the Adaptive Immune Response
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...
01:23Introduction to Lymphatic and Immune System
Immunity is a crucial biological concept about our body's inherent capacity to prevent infections and diseases. A complex network of cells and tissues collectively known as the immune system facilitates this natural defense mechanism. The immune system plays an integral role in maintaining our health and well-being, shielding us from potential health threats.
The immune responses can be categorized into two types: innate and adaptive. Innate immunity comprises nonspecific defenses we are born...

01:16Primary Lymphoid Organs
Primary lymphoid organs are pivotal in the formation, development, and maturation of lymphocytes, the white blood cells that serve as the backbone of our immune system. This crucial function underscores their fundamental role in maintaining our overall health and immunity. The two primary lymphoid organs of prime importance are the red bone marrow and the thymus.
The red bone marrow is a soft, spongy tissue nestled in the interior of long bones such as the humerus and femur. It is the site...

01:15Development of the Lymphatic System
The development of lymphatic tissues and vessels in embryonic life begins around the fifth week. These structures originate from the mesoderm layer, with lymph sacs emerging from developing veins.
The first lymph sacs to form are the paired jugular lymph sacs located at the junction of the internal jugular and subclavian veins. From these sacs, lymphatic capillary plexuses extend to the thorax, upper limbs, neck, and head, eventually forming lymphatic vessels. Each jugular lymph sac maintains a...
