Several efforts have been made to make a list or a map of all human cells. [18] [19] [20] One of the largest and most recent is the HuBMAP (Human BioMolecular Atlas Program). [21] The HuBMAP project has organized 1551 different samples in 17 collections, each dedicated to a different system.
Cytopathology (from Greek κύτος, kytos, "a hollow"; [1] πάθος, pathos, "fate, harm"; and -λογία, -logia) is a branch of pathology that studies and diagnoses diseases on the cellular level. The discipline was founded by George Nicolas Papanicolaou in 1928.
There are four types of granulocytes (full name polymorphonuclear granulocytes): [3] Basophils; Eosinophils; Neutrophils; Mast cells; Except for the mast cells, their names are derived from their staining characteristics; for example, the most abundant granulocyte is the neutrophil granulocyte, which has neutrally staining cytoplasmic granules.
A lymphocyte is a type of white blood cell (leukocyte) in the immune system of most vertebrates. [1] Lymphocytes include T cells (for cell-mediated and cytotoxic adaptive immunity), B cells (for humoral, antibody-driven adaptive immunity), [2] [3] and innate lymphoid cells (ILCs; "innate T cell-like" cells involved in mucosal immunity and homeostasis), of which natural killer cells are an ...
Nitric oxide is then released from the macrophage and, because of its toxicity, kills microbes near the macrophage. [14] Activated macrophages produce and secrete tumor necrosis factor . This cytokine —a class of signaling molecule [ 39 ] —kills cancer cells and cells infected by viruses, and helps to activate the other cells of the immune ...
In vitro, monocytes can differentiate into dendritic cells by adding the cytokines granulocyte macrophage colony-stimulating factor (GM-CSF) and interleukin 4. [19] Such monocyte-derived cells do, however, retain the signature of monocytes in their transcriptome and they cluster with monocytes and not with bona fide dendritic cells.
Illustration of Bowman's capsule, and glomerular capillaries wrapped by podocytes. A podocyte has a complex structure. Its cell body has extending major or primary processes that form secondary processes as podocyte foot processes or pedicels. [6]
