Receptor basics
Receptors are proteins that receive chemical signals from outside the cell. When a ligand binds to a receptor, it causes a cellular response. There are several types of receptors including ion channel linked receptors, G-protein linked receptors, enzyme linked receptors, and nuclear receptors. Nuclear receptors are located within cells and bind lipophilic ligands like steroids and lipids to regulate gene expression. [/SUMMARY]

Cell signaling(signaling through g protien coupled receptors,signal transduct...
Cell signaling involves the communication between cells through chemical signals or direct cell contact. There are four main types of chemical signaling: paracrine (between nearby cells), autocrine (a cell signaling itself), endocrine (over long distances via hormones), and direct contact signaling through structures like gap junctions. G-protein coupled receptors (GPCRs) are the largest family of receptors and detect extracellular molecules, activating intracellular signaling pathways. Upon ligand binding, GPCRs activate G proteins which function as molecular switches to transmit signals within the cell via second messengers like cAMP, IP3 and calcium. This leads to functional changes in the target cell.
Cell signalling
To make multicellular organisms cell must communicate. This communication is mediated by extracellular signal molecules.
Cell signaling -_introduction[1]
Cell signaling involves three main stages - reception, transduction, and response. Reception involves signaling molecules binding to membrane receptors, which leads to conformational changes. Transduction refers to the activation of intracellular signaling pathways through second messengers. Response occurs when downstream effectors are activated, bringing about cellular responses like metabolism, gene expression, and cell differentiation. Precise regulation of cell signaling pathways is essential for normal cell function, and defects can lead to diseases.
Cell Signaling
Cell signaling involves chemical signals binding to cell surface receptors and activating intracellular signal transduction pathways. There are two main ways signals work: by changing the activity of existing proteins or by changing the amount of proteins in the cell. Common types of signals include hormones, growth factors, and neurotransmitters. Signal transduction involves second messengers such as cAMP and IP3 that activate downstream effector proteins like protein kinases. G-protein coupled receptors are a major class of receptors that activate intracellular signaling pathways.
CELL SIGNALING AND PATHWAYS INVOLVED IN CELL SIGNALING AND SOLID TUMORS.
Have Details about the various signaling pathways and signaling molecules and their role in solid tumors.
G proteinโcoupled receptor
G-protein coupled receptors (GPCRs) are integral membrane proteins that detect molecules outside the cell and activate internal signal transduction pathways. They have seven transmembrane domains and couple with G proteins. Ligand binding causes a conformational change in the receptor that activates the G protein, starting signaling cascades. The main signaling pathways are cAMP, phosphatidylinositol, and Rho/ROCK. GPCRs mediate many physiological processes like vision, smell, immune response, and homeostasis. They are also involved in many diseases and are drug targets.
G protein coupled receptor and pharmacotherapeutics
This document provides an overview of G-protein coupled receptors (GPCRs) and their role in cell signaling. It discusses the history and structure of GPCRs, how they interact with G-proteins and secondary messengers like cAMP and IP3 to activate intracellular signaling pathways. These pathways regulate key cellular processes and are targets for drug development to treat diseases. The document also categorizes different classes of GPCRs and summarizes the mechanisms and physiological roles of various secondary messenger systems like cAMP, IP3, and ion channels in signal transduction.
Unit 2 & 4 GPCRs WHOLE UNITS (GENERAL PHARMACOLOGY)
G-protein coupled receptors (GPCRs) are the largest family of membrane receptors and the target of about 30-40% of drugs. They signal through heterotrimeric G proteins which activate downstream effectors like adenylyl cyclase, phospholipase C, and ion channels. This leads to the production of second messengers cyclic AMP, inositol trisphosphate, and diacylglycerol which activate kinases and regulate important cellular processes. Modulation of GPCRs and their associated G proteins and effectors provides opportunities for drug development.
CELL SURFACE RECEPTORS.pptx
This document summarizes different types of cell surface receptors. It begins by defining cell surface receptors and their role in signal transduction across the plasma membrane. It then describes the three main components of receptors and three general categories: ion channel-linked receptors, G-protein-linked receptors, and enzyme-linked receptors. For each category, it provides details on their structure and signaling mechanisms. G-protein-linked receptors are discussed in greatest depth, outlining how they signal through G proteins. Receptor tyrosine kinases are provided as an example of enzyme-linked receptors.
GPCR
G protein coupled receptors (GPCRs) are a large family of cell membrane receptors that are linked to intracellular effector proteins. All GPCRs have seven transmembrane alpha helical segments. The receptors activate intracellular signaling pathways upon binding of an agonist ligand. This leads to the exchange of GDP for GTP on associated G proteins, which then activate downstream effectors to induce cellular responses. The major effector pathways activated by GPCRs are adenylyl cyclase/cAMP, phospholipase C/IP3-DAG, and ion channel regulation.
Signal transduction
The document discusses signal transduction from extracellular signals to cellular responses. It describes the key components of signal transduction pathways, including signal molecules, receptors, conveyers, transducers, and short-term and long-term cellular changes. There are two large classes of signal transduction proteins - G proteins and protein kinases - that transmit signals. Common types of extracellular signaling include endocrine, paracrine, autocrine, and plasma membrane attached proteins. Second messengers like cAMP and Ca2+ transmit signals from many receptors and induce short-term or long-term cellular responses.
Receotor
There are four main types of receptors: G-protein coupled receptors, ligand-gated ion channels, enzymatic receptors like tyrosine kinases, and nuclear receptors that regulate gene expression. G-protein coupled receptors have 7 transmembrane domains and signal through G proteins to activate downstream effectors like adenylate cyclase, phospholipase C, or ion channels. Ligand-gated ion channels open to allow ion flow upon ligand binding. Tyrosine kinase receptors dimerize and autophosphorylate upon ligand binding to phosphorylate substrate proteins. Nuclear receptors directly regulate gene transcription in the nucleus.
TYPES OF RECEPTORS
This document discusses different types of receptors and how they transmit signals. It describes two main domains of receptors - a recognition domain that binds hormones and a coupling domain that generates an intracellular signal. It also discusses three types of cell surface receptors - ion channel receptors, transmembrane receptors, and receptors that are kinases or bind kinases. Steroid hormones can directly activate genes by diffusing into the cell and binding intracellular receptors, which then bind DNA and activate transcription.
CELL SIGNALING
The document discusses three types of cell signaling:
1) Autocrine signaling occurs when a cell produces a messenger that stimulates receptors on its own surface.
2) Paracrine signaling involves messenger molecules that travel short distances to stimulate nearby cells.
3) Endocrine signaling uses messenger molecules that travel long distances through the bloodstream to target distant cells.
Toxicodynamics or pharmacodynamics
1. Toxicology is the study of the biochemical and physiological effects of toxicants on the body and their mechanisms of action, focusing on interactions with target sites. Two factors that determine effect are affinity, how tightly a toxicant binds to a receptor, and intrinsic activity, its ability to activate the receptor and produce a cellular response.
2. Receptors are membrane proteins that toxicants bind to in order to produce effects. There are four main classes of receptors: ligand-gated ion channels, G-protein coupled receptors, enzymatic receptors, and receptors that regulate DNA transcription.
3. G-protein coupled receptors are the largest family and activate distinct effector proteins through G-proteins. Their activation
Antibody
- Antibodies are Y-shaped proteins produced by B cells that recognize and bind to pathogens. They have great diversity and specificity that allows them to target a wide range of antigens.
- Antibodies are composed of two heavy chains and two light chains that form an antigen binding site. The variable regions of the heavy and light chains are responsible for binding to different antigens.
- Monoclonal antibodies are produced from a single clone of B cells and have identical antigen specificity, allowing them to be used as standardized reagents for research and medical purposes. They are produced by fusing B cells with myeloma cells to form immortal hybridomas.
Signal transduction presentation
The document discusses various types of signal transduction in cells. It describes how extracellular signals like hormones bind to cell surface receptors and trigger intracellular signaling pathways using second messengers. These pathways involve G proteins and the production of molecules like cyclic AMP and inositol triphosphates to activate enzymes like protein kinase A and C. This leads to changes in gene expression, metabolism and cell behavior in response to extracellular signals.

THE SACRIFICE HOW PRO-PALESTINE PROTESTS STUDENTS ARE SACRIFICING TO CHANGE T...
The recent surge in pro-Palestine student activism has prompted significant responses from universities, ranging from negotiations and divestment commitments to increased transparency about investments in companies supporting the war on Gaza. This activism has led to the cessation of student encampments but also highlighted the substantial sacrifices made by students, including academic disruptions and personal risks. The primary drivers of these protests are poor university administration, lack of transparency, and inadequate communication between officials and students. This study examines the profound emotional, psychological, and professional impacts on students engaged in pro-Palestine protests, focusing on Generation Z's (Gen-Z) activism dynamics. This paper explores the significant sacrifices made by these students and even the professors supporting the pro-Palestine movement, with a focus on recent global movements. Through an in-depth analysis of printed and electronic media, the study examines the impacts of these sacrifices on the academic and personal lives of those involved. The paper highlights examples from various universities, demonstrating student activism's long-term and short-term effects, including disciplinary actions, social backlash, and career implications. The researchers also explore the broader implications of student sacrifices. The findings reveal that these sacrifices are driven by a profound commitment to justice and human rights, and are influenced by the increasing availability of information, peer interactions, and personal convictions. The study also discusses the broader implications of this activism, comparing it to historical precedents and assessing its potential to influence policy and public opinion. The emotional and psychological toll on student activists is significant, but their sense of purpose and community support mitigates some of these challenges. However, the researchers call for acknowledging the broader Impact of these sacrifices on the future global movement of FreePalestine.
