Routes of Persuasion

Routes of Persuasion

Persuasion is the process of changing our attitude toward something based on some kind of communication. Much of the persuasion we experience comes from outside forces. How do people convince others to change their attitudes, beliefs, and behaviors? What communications do you receive that attempt to persuade you to change your attitudes, beliefs, and behaviors?

Neurons: The Cell Body and the Dendrites

Neurons: The Cell Body and the Dendrites

A typical nerve cell comprises three main components: the cell body, dendrites, and the axon. The cell body, also known as the soma or perikaryon, serves as the central biosynthetic hub housing a nucleus surrounded by cytoplasm containing organelles commonly found in most cells. Notably, Nissl bodies, clusters of the rough endoplasmic reticulum and free ribosomes responsible for protein synthesis, are distinctive features of the neuronal cell body. As neurons age, aggregates of a brown pigment...

Overview of Exosomes

Overview of Exosomes

Exosomes are stable, lipid bilayer-enclosed vesicles capable of crossing biological barriers. They can carry a wide range of molecules required for intercellular communication. Once exosomes are released from the cell where they originated, they enter a recipient cell through various pathways such as fusion, receptor-mediated endocytosis, macropinocytosis, and phagocytosis.
Stahl et al. discovered exosomes in 1983, but the exosomes were initially considered waste products released from the...

Routes of Drug Administration: Parenteral

Routes of Drug Administration: Parenteral

The administration of drugs via parenteral routes allows for direct drug introduction into the systemic circulation, resulting in high bioavailability because the medication bypasses the harsh conditions of the gastrointestinal tract and hepatic metabolism.
The intravenous route (IV) of drug administration can be further categorized into two types. The bolus injection administers the entire dose rapidly, while an intravenous infusion slowly delivers smaller doses steadily.
The IV route is often...

Routes of Drug Administration: Overview

Routes of Drug Administration: Overview

Drug administration involves delivering drugs to the body through various routes, such as enteral, parenteral, and topical.
Enteral administration refers to drugs absorbed through the gastrointestinal tract. They can be swallowed (perorally), placed under the tongue (sublingually), or on the inner lining of the cheeks (buccally). Perorally administered drugs take time to be absorbed and have a slower onset of action. The rectal route is another form of enteral administration, which allows for...

Drug Delivery: Enteral Route

Drug Delivery: Enteral Route

The enteral drug administration involves three primary routes: oral, sublingual, and buccal. Oral ingestion is the most prevalent, safe, economical, and convenient method for drug administration. However, it has certain drawbacks, including limited absorption due to the drug's low water solubility or poor membrane permeability, possible emesis from GI mucosa irritation, destruction of drugs by digestive enzymes or low gastric pH, and irregular absorption along with food or other drugs.

Area of Science:

Immunology
Cell Biology
Biochemistry

Background:

Extracellular vesicles (EVs) mediate intercellular communication.
EVs are categorized as microvesicles and exosomes based on their biogenesis.
Exosomes, particularly from dendritic cells (DCs), play significant roles in immune responses.

Purpose of the Study:

To review the loading mechanisms of antigens and other molecules into exosomes.
To discuss the immunomodulatory functions of exosomes released by antigen-presenting cells.
To highlight advances in exosome biology and their therapeutic potential.

Main Methods:

Literature review of exosome biology and immunology.
Analysis of exosome cargo loading in dendritic cells and antigen-presenting cells.
Discussion of T-cell stimulation by DC-derived exosomes.

Main Results:

Dendritic cell exosomes express MHC class II, co-stimulatory molecules, and loaded antigens.
These exosomes can directly or indirectly stimulate CD4 T-cell proliferation.
Exosome cargo loading is crucial for their immune function.

Conclusions:

Exosomes are potent mediators of immune responses with significant therapeutic promise.
Understanding exosome biogenesis and cargo loading is key to harnessing their potential.
Further research into exosome biology will advance their application in immunotherapy.
