Summary
Basophils, the least common white blood cells, are key players in allergic reactions. Cytokines and chemokines control their function, highlighting their proinflammatory role in type I allergies.
Area of Science:
- Immunology
- Allergy Pathogenesis
Background:
- Basophils are the least abundant leukocytes in human peripheral blood.
- Their precise role in allergic disease pathogenesis has been historically unclear.
- Tissue accumulation and activation suggest significant involvement.
Purpose of the Study:
- To elucidate the regulatory mechanisms of basophil function.
- To understand the specific roles of basophils in type I allergic reactions.
Main Methods:
- Review of recent advances in basophil biology.
- Analysis of the modulatory effects of cytokines and chemokines on basophils.
Main Results:
- Cytokines and chemokines are identified as primary regulators of basophil functions.
- Basophil functions are shown to be differentially modulated by various substances.
- Evidence indicates basophils act as unique effector cells.
Conclusions:
- Basophils, when exposed to allergens and regulatory substances, exhibit distinct proinflammatory roles.
- These cells are crucial effector cells in type I allergic reactions.

Differentiation of Common Myeloid Progenitor Cells
Common myeloid progenitors (CMPs) are oligopotent cells that can differentiate into granulocytes and macrophages. Granulocytes and macrophages are essential for protecting the body against bacterial, viral, or fungal infections. They migrate from the bone marrow into the circulating blood to reach specific tissue sites where they differentiate and help in immune surveillance. However, they survive only for a few days and must be continuously made available to the organism to maintain a robust...
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...

Overview
Classification of Leukocytes
Leukocytes are classified into two groups based on the presence or absence of cytoplasmic granules. Granular leukocytes, which contain granules, belong to the myeloid lineage and are divided into three subtypes: neutrophils, eosinophils, and basophils. These cells are roughly spherical and characterized by the granules in their cytoplasm.
Neutrophils are the most abundant type of granular leukocytes, comprising 50-70% of all leukocytes. They feature small, evenly distributed granules and a...

Regulation of Hematopoietic Stem Cells
All blood and immune cells are produced from the multipotent hematopoietic stem cells (HSCs) by the process of hematopoiesis. However, they all have a limited life span. In addition, many are depleted in immune surveillance or combatting an injury or infection. This makes blood one of the most regenerative tissues. Hematopoiesis helps replenish these blood and immune cells, restoring the body's normal functioning. However, overproduction of blood and immune cells can make them cancerous or...
B Cell Activation and Differentiation
The adaptive immune response, a sophisticated defense mechanism, relies on the activation and differentiation of B lymphocytes, or B cells. These processes enable our bodies to mount a tailored response against specific pathogens such as bacteria, free virus particles, toxins, and parasites.
When naive B cells encounter a specific antigen that can bind to the B cell receptor (BCR) on their surface, they undergo sensitization to respond to the antigen's presence. Sensitization begins with...
