Summary
The miR-29 family, crucial microRNAs (miRs), regulates adaptive immunity by controlling T cell production, polarization, and B cell transformation. These miRs are key targets for immune modulation and potential therapies.
Area of Science:
- Immunology
- Molecular Biology
- Genetics
Background:
- MicroRNAs (miRs) are key regulators of gene expression.
- The miR-29 family, comprising miR-29a, miR-29b-1, miR-29b-2, and miR-29c, is expressed in immune cells like T cells, B cells, and dendritic cells.
- These miRs are implicated in regulating key immunological pathways.
Purpose of the Study:
- To investigate the role of the miR-29 family in adaptive immunity.
- To elucidate the function of miR-29 in T cell development, polarization, and B cell transformation.
Main Methods:
- Generation of in vivo molecular tools targeting the miR-29 family.
- Analysis of miR-29's impact on thymic T cell production.
- Assessment of miR-29's role in T cell polarization post-activation.
- Evaluation of miR-29's influence on B cell oncogenic transformation.
Main Results:
- The miR-29 family critically controls the threshold for infection-associated thymic involution, impacting T cell production.
- miR-29 establishes a neutral threshold for T cell polarization after activation.
- The miR-29 family plays a role in setting the threshold for B cell oncogenic transformation.
Conclusions:
- The miR-29 family acts as potent immune modulators in adaptive immunity.
- These miRs have been exploited by viral mimics and hold potential for future therapeutic interventions.

01:40Cell-mediated Immune Responses
Overview
01:26Antigens Involved in Adaptive Immunity
An antigen is any substance the immune system identifies as foreign and potentially harmful to the body, prompting an immune response. Antigens have two functional properties: immunogenicity and reactivity. Immunogenicity is the ability of an antigen to stimulate a specific immune response. At the same time, reactivity describes the antigen's ability to react with the cells and antibodies produced in response to it.
Complete Antigens
Complete antigens possess both immunogenicity and reactivity.

01:20Special Features of Adaptive Immunity
The adaptive immune system, a crucial component of the overall immune response, offers a highly specialized defense against pathogens. It involves specific cell types and features, enabling it to combat infections effectively and efficiently.
The primary cell types involved in adaptive immunity are T cells and B cells. Each type has a unique role in defending the body against pathogens. T cells are responsible for cell-mediated immunity. They identify and eliminate infected cells directly,...

Overview
01:23The Antiviral System of Bacteria and Archaea: CRISPR
CRISPR stands for Clustered Regularly Interspaced Short Palindromic Repeats is a adaptive immune system found in bacteria and archaea that protects against viral infections. This system enables prokaryotic cells to identify, remember, and neutralize foreign genetic elements, primarily bacteriophages, by storing fragments of the invader’s DNA as a genetic memory.The CRISPR immune response begins during an initial infection. Cas (CRISPR-associated) proteins play a central role in this defense.
01:23Cells of the Adaptive Immune Response
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...
