Microleucocyte: An Overview

Introduction

Microleucocytes, also known as microcytic leucocytes, are a type of white blood cell that plays a crucial role in the immune system. They are characterized by their small size and granular cytoplasm. This article will provide an overview of microleucocytes, including their function, significance, and classification.

Function and Significance

Microleucocytes are an essential component of the immune system, responsible for defending the body against infections and diseases. They are produced in the bone marrow and circulate in the bloodstream, where they can migrate to sites of infection or injury. Once at these sites, microleucocytes can phagocytose bacteria, fungi, and other pathogens, thus eliminating them from the body.

One of the key functions of microleucocytes is to release chemical signals, known as cytokines, which regulate the immune response. These cytokines can activate other immune cells, such as macrophages and natural killer cells, enhancing the body's overall defense mechanisms. Additionally, microleucocytes can communicate with epithelial cells, which line the surfaces of tissues and organs, to regulate the permeability of these barriers and control the movement of substances in and out of the body.

Classification

Microleucocytes can be classified into two main types: basophils and eosinophils. Basophils are characterized by their large, dark purple granules and make up a small percentage of the total white blood cell count. They are primarily involved in allergic reactions and the release of histamine, which causes blood vessels to dilate and increases vascular permeability. Eosinophils, on the other hand, have smaller, orange
