Summary
Mathematical models for lymphocyte dynamics are updated to include inherited traits. The new Cyton2 model accurately captures cell behaviors, improving data analysis for adaptive immune responses.
Area of Science:
- Immunology
- Computational Biology
- Mathematical Modeling
Background:
- Lymphocytes (B and T cells) drive adaptive immunity through clonal expansion and memory formation.
- Existing mathematical models often assume independent cell behavior, neglecting familial correlations.
- Recent findings indicate inheritance of timed fate changes in lymphocyte progeny, necessitating revised modeling approaches.
Purpose of the Study:
- To develop a new mathematical model that incorporates within-family inheritance of lymphocyte fate.
- To revise existing modeling paradigms for more accurate information extraction from lymphocyte studies.
- To validate the new model's consistency with experimental observations and its utility in data analysis.
Main Methods:
- Long-term live-cell imaging of stimulated murine B and T cells in vitro.
- Development of the Cyton2 mathematical model based on observed inheritance phenomena.
- Validation using high-throughput flow cytometry data and complex mixed stimulation experiments.
Main Results:
- Cyton2 successfully encapsulates key within-family inheritance phenomena in lymphocytes.
- The model demonstrates consistency with fine-grained experimental features.
- Cyton2 shows robustness in parameter estimation and biological meaning extraction from complex data.
- The model is neither overparameterized nor computationally inefficient.
Conclusions:
- Cyton2 provides a more experimentally aligned mathematical model for lymphocyte population dynamics.
- The model enhances the extraction of biological insights from lymphocyte studies.
- This work challenges the assumption of independent cell behavior in lymphocyte modeling.

Cystic fibrosis (CF), an autosomal recessive disorder, significantly affects the function of exocrine glands. This genetically inherited disease is characterized by the production of thick and sticky mucus, which can severely affect various organs and systems in the body.
CF is primarily caused by a genetic mutation in a chromosome 7 gene coding for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. The most common gene mutation leading to CF is the ΔF508 mutation,...

01:22T Cell Activation and Clonal Selection
3.0K
T cells are integral to our adaptive immune system, recognizing and effectively responding to foreign antigens. T cell activation and clonal selection are pivotal in orchestrating this immune response. This article elucidates these mechanisms, detailing the roles of cluster of differentiation (CD) markers, major histocompatibility complex (MHC) molecules, costimulatory signals, and the process of clonal selection.

55.7K
In 1866, Gregor Mendel published the results of his pea plant breeding experiments, providing evidence for predictable patterns in the inheritance of physical characteristics. The significance of his findings was not immediately recognized. In fact, the existence of genes was unknown at the time. Mendel referred to hereditary units as “factors.”

03:17Inheritance of Chromatin Structures
6.4K
Epigenetics is the study of inherited changes in a cell's phenotype without changing the DNA sequences. It provides a form of memory for the differential gene expression pattern to maintain cell lineage, position-effect variegation, dosage compensation, and maintenance of chromatin structures such as telomeres and centromeres. For example, the structure and location of the centromere on chromosomes are epigenetically inherited. Its functionality is not dictated or ensured by the underlying...

01:23Cells of the Adaptive Immune Response
3.2K
The T and B lymphocytes of the adaptive immune system develop from common lymphoid progenitor cells in the bone marrow. These progenitors give rise to precursors that eventually develop into both T and B lymphocytes. As these precursors mature, they gain the ability to detect and respond to foreign antigens in the body, a process known as immunocompetence. Additionally, these precursors acquire self-tolerance, a process that ensures they do not react to self-antigens. This intricate system...

01:09Mutation, Gene Flow, and Genetic Drift
59.3K
In a population that is not at Hardy-Weinberg equilibrium, the frequency of alleles changes over time. Therefore, any deviations from the five conditions of Hardy-Weinberg equilibrium can alter the genetic variation of a given population. Conditions that change the genetic variability of a population include mutations, natural selection, non-random mating, gene flow, and genetic drift (small population size).
