The pancreas, a vital organ within the abdominal cavity, plays dual roles in the digestive and endocrine systems, collaborating with exocrine and endocrine cells to maintain optimal digestion and blood sugar levels. Exocrine function is carried out by acinar cells, organized into clusters known as acini. These cells contribute to digestion by releasing substantial quantities of enzyme-rich, alkaline digestive juices. Concurrently, the dispersed clusters of endocrine cells throughout the...

Functional Assessment of Antibody-Secreting B Cells Using ELISpot Assay
0 Views •
2025
This video demonstrates the use of the ELISpot assay to assess the function of antibody-secreting B cells, ASCs. The antibodies secreted by the ASCs interact with the membrane-bound polyclonal antibody fragments, which are detected by the enzyme-conjugated IgG or IgM antibodies. The colored spot produced in each well indicates the presence of the specific antibody's isotype, which correlates with the B cells' secretory activity.

Inter-cellular communication is critical for controlling various physiological activities within and outside the cell. This paper describes a protocol for measuring the spatio-temporal nature of single cell secretions. To achieve this, a multidisciplinary approach is used which integrates label-free nanoplasmonic sensing with live cell imaging.
FAQs
Mucin production follows an intracellular pathway: the endoplasmic reticulum and Golgi apparatus synthesize and process these large glycoproteins, after which secretory vesicles package them. The vesicles store material for release at the cell surface, where exocytosis releases it. This sequence links organelle function to delivery of mucus.
Once exocytosis releases mucins, contact with water causes them to expand into a hydrated gel. This physical change is important because the secreted material becomes a mucus layer rather than remaining concentrated inside vesicles. The resulting gel supports surface protection, particle and pathogen trapping, and lubrication of internal tissues.
Changes in goblet-cell number or activity can alter how much protective mucus is available at an epithelial surface. In the respiratory tract, such changes may influence airway inflammation; in the intestine, they may be associated with intestinal diseases. Their responses can also vary with environmental or infectious stress, making them useful context for interpreting epithelial health.
Goblet cells occur in epithelial tissues including the respiratory and gastrointestinal tracts, where mucus serves important surface-protection roles. In either setting, the hydrated layer can trap particles and pathogens while reducing friction. Studying their location therefore connects cell biology with protection and lubrication at internal body surfaces.
Because their abundance and secretory activity can change, goblet cells provide a cellular focus for studying airway inflammation, intestinal diseases, and epithelial responses to environmental or infectious stress. Investigators can relate alterations in these cells to changes in mucus production and surface defense. This makes them relevant to tissue-level and disease-related biology.
A biologically informative examination can follow the sequence from mucin synthesis in the endoplasmic reticulum and Golgi apparatus to vesicle packaging and exocytosis, then consider hydration outside the cell. It should also note tissue location and changes in cell number or activity. Together, these features connect intracellular events with mucus-based protection and disease-relevant outcomes.
