Extrinsic Pathway of Apoptosis || 4K Animation
The extrinsic pathway of apoptosis activated through Fas death
receptors. Trimeric Fas ligands on the surface of a killer lymphocyte interact with trimeric Fas receptors on the surface of the target cell, leading to clustering of several ligand-bound receptor trimers (only one
trimer is shown here for clarity). Receptor clustering activates death domains on the receptor tails, which interact with similar
domains on the adaptor protein FADD (FADD stands for Fas-associated death domain). Each FADD protein then recruits an initiator caspase (caspase-8) via a death effector domain on both FADD and
the caspase, forming a death-inducing signaling complex (DISC). Within the DISC, two adjacent initia...

HIV Life Cycle HIV, the Human Immunodeficiency Virus, replicates through a complex series of steps that exploit the host cell's own machinery. Here's a closer look at the viral ballet from a molecular biology perspective: 1. Binding: This intricate waltz begins with viral envelope glycoproteins, gp120, specifically binding to CD4 receptors and a co-receptor (usually CCR5 or CXCR4) on the surfac...

#cellbiology #apoptosis #cancer Caspase activation during apoptosis. An initiator caspase contains a protease domain in its carboxy-terminal region and a small protein interaction domain near its amino terminus. It is initially made in an inactive, monomeric form, sometimes called procaspase. Apoptotic signals trigger the assembly of adaptor proteins carrying multiple binding sites for the casp...
MAPK Signaling Pathway || Animated Explanation
Просмотров 2612 месяца назад
#cellsignaling #mitogen #cellcycle Mitogens are signaling molecules that bind to cell-surface receptors and initiate a cascade of intracellular signaling pathways that are essential for cell growth and division. One of the key pathways activated by mitogens involves the small GTPase Ras. Upon activation, Ras engages the MAP kinase (MAPK) cascade, a series of protein kinases that transmit the gr...
Auxin Signaling Animation || Auxin Hormone
Просмотров 5892 месяца назад
Auxin Signaling Mechanism: In the Absence of Auxin: Aux/IAA Proteins: These are transcriptional repressor proteins that, in the absence of auxin, bind to and inhibit auxin-response factors (ARFs). ARFs: ARFs are transcription regulatory proteins essential for the transcription of auxin-responsive genes. However, without auxin, they are suppressed by Aux/IAA proteins, preventing the expression o...
How DNA damage arrests the cell cycle
Просмотров 2492 месяца назад
When DNA is damaged, various protein kinases are recruited to the site of damage and initiate a signaling pathway that causes cell-cycle arrest. The first kinase at the damage site is either ATM or ATR, depending on the type of damage. Additional protein kinases, called Chk1 and Chk2, are then recruited and activated, resulting in the phosphorylation of the transcription regulatory protein p53....

In this animation video, you will learn about TNF-α signaling, a key process that controls whether a cell lives or dies. TNF-α is a molecule that can trigger inflammation and immune responses, but also influence the fate of the cell by activating the TNF receptor. The TNF receptor can initiate two different pathways: one that leads to apoptosis, or programmed cell death, and another that leads ...

Explanation is good but I have one doubt that Telomerase adds more nucleotide to the template means it is indirectly increasing the genetic constituent It should be removed. How it's possible
This is the best video thankyou so much!
