Summary
Long-lived plasma cells (LLPCs) maintain high antibody titers for decades after smallpox vaccination. Understanding differences between mouse models and humans is crucial for studying LLPCs and lifelong immunity.
Area of Science:
- Immunology
- Infectious Diseases
Background:
- High antibody titers against smallpox persist for over 70 years post-vaccination, indicating long-term immunity.
- Long-lived plasma cells (LLPCs) are crucial for maintaining persistent antibody levels in the absence of active infection.
Purpose of the Study:
- To review current knowledge on LLPCs and their role in long-lasting immunity.
- To compare LLPC function and characteristics between mouse models and humans.
Main Methods:
- Review of existing literature on LLPCs in immunology.
- Comparative analysis of data from mouse models and human studies.
Main Results:
- LLPCs are responsible for sustained antibody production long after pathogen eradication.
- Significant anatomical and physiological differences exist between mice and humans, potentially impacting LLPC function.
Conclusions:
- LLPCs are key to lifelong immunity against diseases like smallpox.
- Direct extrapolation of mouse LLPC data to humans requires careful consideration of interspecies differences.

3.8K
The human body utilizes protein buffer systems to maintain a stable pH. These systems capitalize on the dual role of amino acids, which can act as acids or bases by accepting or releasing hydrogen ions in response to pH changes. Protein buffer systems are particularly significant in the extracellular fluid (ECF) and intracellular fluid (ICF) of active cells, where structural and functional proteins provide substantial buffering capacity.

2.7K
Different fluorescence-based techniques are used to study the protein dynamics in living cells. These techniques include FRAP, FRET, and PET.
Fluorescent recovery after photobleaching (FRAP) is a fluorescent-protein-based detection technique used to quantify protein movement rates within the cell. This method exposes a small portion of the cell to an intense laser beam. The laser beam causes permanent photobleaching of the fluorophore-tagged proteins in the exposed region. As the bleached...

01:24Composition of Blood Plasma
8.5K
Blood plasma is a fluid that contains approximately 92% water and 8% solutes. The solutes include various types of proteins, which constitute about 7% of the total solutes in the plasma. The high-molecular-weight proteins—albumins, globulins, and fibrinogen—are essential to plasma function. Albumins, making up about 60% of the plasma proteins, maintain the osmotic balance within blood vessels by preventing excessive water leakage. Additionally, albumins serve as carrier proteins,...

01:22Enlargement of the Plasma Membrane
2.4K
Cell division and enlargement are processes that require precise control. The control ensures that cell division cannot proceed unless the cell has grown to a specific size. A spherical, dividing cell requires an approximately 1.6X increase in its surface area to double its volume. The secretory pathway also has a significant role in cell membrane enlargement. Secretory vesicles that bud off from the Golgi apparatus and later fuse with the plasma membrane during exocytosis are a major source of...

The plasma membrane is an essential cellular structure responsible for maintaining cellular integrity and regulating the selective transport of molecules. While bacteria and archaea share the fundamental function of plasma membranes, their structural and molecular differences reflect adaptations to distinct ecological and physiological challenges.Bacterial Plasma MembranesBacterial plasma membranes are predominantly composed of phospholipids with fatty acid chains ester-linked to a glycerol...

01:29Drug Distribution: Plasma Protein Binding
8.8K
Drugs predominantly attach to plasma proteins, with only a small percentage remaining unbound. The unbound portion can be calculated as one minus the bound fraction. Acidic drugs form large, inactive complexes by reversibly binding to plasma albumin, which prevents them from diffusing across biological barriers. These drug-protein complexes act as reservoirs for the drugs. As the concentration of unbound drugs decreases, these complexes quickly dissociate to release the free drug, maintaining...
