Leukocytes are differentiated white blood cells derived from either myeloid or lymphoid precursor cells. Cells of myeloid lineage include monocytes and granulocytes. Monocytes include macrophages and dendritic cells, specialized phagocytes that function as antigen-presenting cells (APCs) to initiate an adaptive immune response. Granulocytes include neutrophils, which are also phagocytes but not APCs, and mast cells, which are important inducers of the inflammatory response but may also cause allergic reactions. Lymphocytes include B and T cells, which facilitate adaptive immunity, and natural killer cells, which play a key role in destroying virus-infected and cancerous host cells. What is the origin of the phagocytes and lymphocytes active in the immune response? Track the maturation of B cells and T cells.

Expert Solution & Answer

Summary Introduction

Leukocytes (White blood cells) are derived from either myeloid or lymphoid precursor cells. Cells which are derived from myeloid lineage include monocytes and granulocytes. Monocytes comprise macrophages and dendritic cells which are specialized phagocytic cells called antigen presenting cells (APCs). Granulocytes include neutrophils and mast cells. Lymphocytes include B-cells (B leukocytes), T-cells (T leukocytes), and natural killer cells.

Explanation of Solution

Phagocytes are originated from the myeloid lineage and are specialized antigens presenting cells which help in developing adaptive immune responses in the body of an organism. These specialized cells comprise macrophages and natural killer cells. These phagocytic cells engulf and transport pathogen to the lymphocytes in order to generate an adaptive immune response. In contrast to this, lymphocytes originated from lymphoid lineage and comprise B-cells, T-cells, and natural killer cells.

B-cells mature and originate inside the bone marrow. B-cells are also specialized antigen presenting cells like those of macrophages and dendritic cells. In addition, these B-cells also act as a precursor of antibody-producing plasma cells. T-cells initially start their development process in bone marrow but they migrate to thymus cells for further maturation.

In addition to phagocytosis, neutrophils use a process called NETs. Which one of the following describes this process? Group of answer choices A. NETs is a neutrophil process that activates the complement system of proteins, which destroys pathogens. B. A net-like structure of DNA, histones, lactoferrins, gelatinase, cathepsin G, and myeloperoxidase is secreted at pathogens. Together these chemicals destroy pathogens. C. NETs works when neutrophils secrete major basic proteins onto pathogens, destroying the pathogens' cell membranes. D. NETs are chemicals secreted by neutrophils that trigger the rapid maturation of lymphoid stem cells into lymphocytes.

These are cells which give rise to the lymphoid lineage of white blood cells or leukocytes- the ILCs, NK cells and the T and B lymphocytes. _____________3. These are cells which rise to the myeloid lineage which comprise to the rest of the leukocytes, the erythrocytes, and the megakaryocytes that produce platelets important in blood clotting. _____________4. This is the first line of defense which consists of a surface barrier and internal structures that employ physical and biochemical strategies to get rid of many microorganisms before they can invade body tissues. _____________5.
