    Multiple myeloma derives from the precursor cells of B lymphocytes, and it alters the host's immunity. It suppresses polyclonal antibody production, reduces CD4/8 ratio, and suppresses NK cells and dendritic cells. Myeloma cells and bone marrow stromal cells produce IL-6 and VEGF, which also alters the immunological microenvironment. While most anti-cancer agents suppress the host's immunity deeply, immunomodulatory drugs (IMiDs) activate T and NK cells, which induce anti-myeloma effects. Currently several bisphosphonates and anti-RANKL antibody are used to prevent skeletal-related events in myeloma, and these agents also have some impacts to the immune system. To enhance therapeutic strategies of myeloma, it is crucial to uncover the interactions of the immunological microenvironment and these agents in myeloma patients.

    Disorders of Leukocytes

    Leukocyte disorders can lead to either leukopenia, characterized by an abnormally low leukocyte count, or leukocytosis, marked by a very high leukocyte number.
    Leukopenia may result from bone marrow disorders, autoimmune diseases, and infectious diseases. For example, conditions such as multiple myeloma and aplastic anemia can impair the bone marrow's ability to produce adequate leukocytes. Similarly, autoimmune diseases like lupus and viral infections such as HIV can prompt the immune...

    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...

    Bone Marrow Sampling and Transplants

    Bone marrow transplant is a potential cure for several diseases, including cancer and specific genetic disorders. Notably, this procedure is applicable for patients suffering from aplastic anemia, certain types of leukemia, severe combined immunodeficiency disease (SCID), Hodgkin's disease, non-Hodgkin's lymphoma, multiple myeloma, thalassemia, sickle-cell disease, and certain cancers.
    The transplant begins with high doses of chemotherapy and radiation treatment, which aim to destroy...

    Immunodeficiency Diseases

    Immunodeficiency disorders are conditions in which the immune system's ability to fight infectious disease and cancer is compromised or entirely absent. The immune system comprises a complex network of cells, tissues, and organs that work together to protect the body from potentially harmful invaders. When this system is deficient or not functioning properly, it leaves the body susceptible to infections, diseases, or other complications.
    There are three main causes of immunodeficiency...

    Multiple Sclerosis l: Introduction

    Multiple sclerosis is a chronic autoimmune disease of the central nervous system (CNS) that affects the brain, spinal cord, and optic nerves. It is an inflammatory demyelinating disorder and a leading cause of neurological disability in young adults.EpidemiologyMS commonly begins between 20 and 40 years of age and is twice as common in women. Its exact cause remains unclear, but genetic susceptibility contributes, with higher risk in first-degree relatives and identical twins. A greater...

    Chronic Kidney Disease II: Clinical Manifestations

    Chronic Kidney Disease (CKD) progressively impairs multiple body systems due to the accumulation of uremic toxins, which disrupt cellular functions across various organs.Neurologic symptomsNeurologic symptoms often arise early in CKD, as uremic toxin buildup drives changes in cognitive and motor functions. Patients frequently experience fatigue, headache, confusion, difficulty concentrating, and, in severe cases, seizures. Peripheral neuropathy commonly manifests as burning sensations in the...
