In the early stages of apoptosis changes occur at the cell surface, which until now have remained difficult to recognize. (scienceopen.com)
Translocation of PS to the external cell surface is not unique to apoptosis, but occurs also during cell necrosis. (scienceopen.com)
The difference between these two forms of cell death is that during the initial stages of apoptosis the cell membrane remains intact, while at the very moment that necrosis occurs the cell membrane looses its integrity and becomes leaky. (scienceopen.com)
Therefore the measurement of Annexin V binding to the cell surface as indicative for apoptosis has to be performed in conjunction with a dye exclusion test to establish integrity of the cell membrane. (scienceopen.com)
Unexpectedly, however, at later times (6 and 24 hours) NETs apparently triggered a cell death process in these APCs by a caspase- and Apoptosis induced factor (AIF)-dependent pathway, suggesting mitochondrial damage. (springeropen.com)
At lower NSC631570 concentrations malignant cells die as a result of apoptosis, at higher concentrations the formation of microtubules is prevented und polyploidy occurs (62). (ukrin.com)

Positive regulator plasma protein properdin is critical for the alternative pathway of complement. (hycultbiotech.com)

These agents also damage all tissues (e.g., gut epithelium, bone marrow) where rapid cell division is occurring, creating other undesirable side effects, thus often may not be suitable for use in medical nanorobotics. (nanomedicine.com)
In due course, the stem cells in the bone marrow reconstitute the peripheral lymphoid system but the newly formed T cells seem to accept the graft as self [ 403 ]. (nanomedicine.com)
They arise from the lymphoid stem cell line in the bone marrow and differentiate into two distinct but inter-related cell types: the B lymphocytes and T lymphocytes. (pediagenosis.com)
While T and B lymphocytes are generated from lymphoid stem cells in the bone marrow, they do not stay there to mature. (pediagenosis.com)

The proteins account for 5% of the serum globulin fraction. (dadamo.com)
Target cells for MAC action may be heterologous erythrocytes, nucleated cells (autologous or foreign), bacteria (Gram-negative, susceptible to serum), microscopic fungi, viruses with a surface envelope and virus-infected cells. (dadamo.com)

Morbillivirus genomes encode 6 structural proteins in the following order: nucleocapsid (N) protein, phosphoprotein (P), matrix (M) protein, hemagglutinin (H) protein, fusion (F) protein, and large polymerase (L) protein ( 2 ). (cdc.gov)

At 8 weeks of gestation, the trophoblast cells invade from the placenta into the maternal tissue and into the uterine arteries. (frontiersin.org)
These endovascular trophoblast cells facilitate the remodeling of spiral uterine arteries, which is essential for a healthy pregnancy. (frontiersin.org)
Invading trophoblast cells will encounter maternal complement system (C) in the decidua and in the intervillous space. (frontiersin.org)

1 - 3 The pathological features of TMA are endothelial cell damage and microthrombi formation in small blood vessels, leading to a partial or complete obstruction of the vessel lumina. (jrheum.org)
The overactive system attacks cells known as endothelial cells that line small blood vessels in the kidneys. (medlineplus.gov)

Within the cell, TSPO is predominantly located in mitochondria, specifically in the outer mitochondrial membrane. (uni-regensburg.de)
One of these plasma membrane alterations is the translocation of phosphatidylserine (PS) from the inner side of the plasma membrane to the outer layer, by which PS becomes exposed at the external surface of the cell. (scienceopen.com)
Hence this protein can be used as a sensitive probe for PS exposure upon the cell membrane. (scienceopen.com)
These results suggest that the MCP + DAF and MCP + CD59 combinations could be more effective than DAF + CD59 in protecting the NIH 3T3 cells from injury caused by complement-dependent cytolysis, whereas MCP or DAF alone is stronger than CD59 alone in inhibiting membrane attack complex formation. (ectrx.org)
MAC causes channel formation to the cell membrane of pathogen, leading to death of microorganisms. (biomedcentral.com)

This dual role of the complement must be nature's rule just like normal hemostasis, which protects human lives in external bodily injury, but also may harm human lives in intravascular injury through thrombogenesis. (biomedcentral.com)

While checkpoint immunotherapy has revolutionized the treatment of patients with non-small cell lung cancer (NSCLC), a subset of patients develop hyperprogressive disease, yet the pathological features or underlying mechanisms for this association have yet to be fully understood. (aacr.org)
In vitro tests showed that after incubation with NSC631570 normal liver cells and Ehrilch tumour ascitic cells demonstrate different oxygen consumption: after initial increase, oxygen consumption in cancer cells falls to zero whereas oxygen consumption in normal cells returns to normal and the cells remain undamaged (38). (ukrin.com)
This study brought the first indications that, in contrast to its starting substances thiotepa (a well known cytostatic agent) and greater celandine alkaloids, NSC631570 is in fact only toxic against cancer cells and not against normal cells. (ukrin.com)
The preparation has shown that the problem can be solved and has changed our ideas about healthy and cancer cells. (ukrin.com)
This means that NSC631570 can differentiate between healthy and malignant cells, a feature not yet managed by other anti-cancer drugs. (ukrin.com)
