First, Weismann was emphasizing death, per se, as the "beneficial" quality that caused evolution of the death mechanism. Other theorists pointed out that few animals in the wild live long enough to die of old age and that therefore a programmed death mechanism would very seldom actually operate.
Programmed cell-death (PCD) is death of a cell in any form, mediated by an intracellular program.In contrast to necrosis, which is a form of cell-death that results from acute tissue injury and provokes an inflammatory response, PCD is carried out in a regulated process which generally confers advantage during an organism's life-cycle.
Blocking programmed death protein 1 (PD-1) negative immune receptor has produced remarkable progress in treating patients with advanced cancers, such as melanoma, lung, head and neck, kidney, bladder, Hodgkin’s disease, mismatch repair deficient colon cancer, liver and ovarian cancer with high mutational burden, etc. We aim to investigate expression profiles of HER2 and programmed death ligand 1 (PD‐L1) in gastric NEC to test the potential applicability of drugs targeting these molecules. Methods and results Expression levels of HER2 and PD‐L1 were evaluated in 25 gastric NECs, including 10 pure NECs and 15 mixed adenocarcinoma–NECs, and a combined positive score (CPS) was used to evaluate PD‐L1 Diatoms are important phytoplankton and contribute greatly to the primary productivity of marine ecosystems. Despite the ecological significance of diatoms and the importance of programmed cell death (PCD) in the fluctuation of diatom populations, little is known about the molecular mechanisms of PCD triggered by different nutrient stresses.

This is best reflected by the number of scientific articles on cell death over the last 3 Programmed cell death protein 1, also known as PD-1 and CD279 (cluster of differentiation 279), is a protein on the surface of cells that has a role in regulating the immune system 's response to the cells of the human body by down-regulating the immune system and promoting self-tolerance by suppressing T cell inflammatory activity. Targeting programmed death 1 (PD-1) or its ligand (PD-L1) offers significant clinical benefits in many cancers. One emerging biomarker of response to anti–PD-1/PD-L1 therapy is the tumor mutational burden, 1,2 which quantifies the number of somatic mutations in the tumor. Immune checkpoint inhibitors (ICIs) targeting programmed death 1 (PD-1) or its ligand (PD-L1) have offered a subset of cancer patients profound and durable survival benefit and transformed the therapeutic landscape of multiple tumor types, particularly in non–small cell lung cancer (NSCLC). 1-6 However, the proportion of patients with NSCLC who respond to ICIs is low; response to the anti Programmed cell death (PCD) is the deliberate suicide of an unwanted cell in a multicellular organism.

Tp53 can initiate apoptosis (i.e., programmed cell death) if DNA damage proves to be irreparable and It can activate DNA repair proteins when DNA has sustained damage.

Two discoveries brought cell death from obscurity to a major field of research: identification of components of the cell death control and effector mechanisms, and linkage of abnormalities in cell death to human disease, in particular cancer. PROGRAMMED CELL DEATH (APOPTOSIS ) 1. 1 PROGRAMMED CELL DEATH (APOPTOSIS ) Introduction: – Apoptosis is a naturally occurring process by which a cell is directed to programmed cell death. – The name Apoptosis is a Greek name describing falling of leaves. Programmed cell death (PCD) is mediated by several cellular gene expression events, which are mainly divided into apoptosis, autophagy, necroptosis, and ferroptosis 1.Caspase is a key factor This would mean that there is a programmed-cell-death and natural age limit to cells and, thus, people. Together, the cellular theories of aging look at the mechanistic aging of a cell. Programmed cell death protein 1, also known as PD-1 and CD279 (cluster of differentiation 279), is a protein on the surface of cells that has a role in regulating the immune system's response to the cells of the human body by down-regulating the immune system and promoting self-tolerance by suppressing T cell inflammatory activity.
