Adaptación de la citometría de flujo para el estudio de la estacionalidad de las células inmunitarias en murciélagos
bioRxiv : the preprint server for biology
|February 12, 2026
Resumen
La citometría de flujo de campo permite perfilar las células inmunitarias de la vida silvestre. Las células inmunitarias de los murciélagos muestran cambios estacionales, con un aumento de las células adaptativas durante la migración y variación de los neutrófilos con la reproducción.
Área de la Ciencia:
- Inmunología de la vida silvestre
- Citometría de campo
- Inmunidad celular de mamíferos
Sus antecedentes:
- La evaluación de la inmunidad de la vida silvestre es crucial para comprender los impactos de los factores estresantes y los riesgos de enfermedades zoonóticas.
- Los estudios de la vida silvestre enfrentan desafíos debido a la logística y la escasez de reactivos específicos para cada especie.
- La citometría de flujo es una herramienta poderosa para perfilar la inmunidad celular, pero normalmente está limitada al laboratorio.
Objetivo del estudio:
- Adaptar la citometría de flujo para uso en campo en la investigación de la vida silvestre.
- Investigar la estacionalidad de las células inmunitarias en murciélagos migratorios de cola libre mexicanos (Tadarida brasiliensis).
- Establecer un método para perfilar la inmunidad celular utilizando pequeños volúmenes de sangre y tiempos de retención de muestras prolongados.
Principales métodos:
- Se adaptó la citometría de flujo para la aplicación en campo utilizando anticuerpos validados (CD3, CD79a, MHCII, CD11b).
- Se cuantificaron los linfocitos T, linfocitos B, macrófagos y neutrófilos en murciélagos de cola libre mexicanos.
- Se compararon los perfiles de leucocitos de citometría de flujo con la hematología tradicional.
Principales resultados:
- La citometría de flujo proporcionó un perfil de leucocitos superior en comparación con la hematología.
- Se observó una estacionalidad significativa de las células inmunitarias en los murciélagos.
- Las células inmunitarias adaptativas aumentaron de la primavera al otoño; los neutrófilos alcanzaron su punto máximo durante la reproducción.
Conclusiones:
- La citometría de flujo basada en campo es un método viable para estudios de inmunología de la vida silvestre.
- Las poblaciones de células inmunitarias de los murciélagos exhiben una dinámica estacional distinta, particularmente en torno a la migración y la reproducción.
- Esta investigación proporciona una base para aplicaciones más amplias de la citometría de flujo en campo para la evaluación de la salud de la vida silvestre.

Cells of the Adaptive Immune Response
9.1K
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...

Introduction to Innate and Adaptive Immunity
9.9K
The human immune system is a complex defense mechanism that protects the body from harmful pathogens and foreign substances. It comprises two crucial components: innate and adaptive immunity.
Innate immunity is the body's natural, nonspecific defense system that acts quickly to protect against pathogens. It incorporates physical barriers like skin and mucous membranes and cellular elements such as phagocytes and natural killer cells. This part of our immune system provides an immediate,...

Flow Cytometry
16.5K
The development of flow cytometry techniques began in 1934 with initial attempts by Andrew Moldavan, a bacteriologist who counted the cells in a flowing capillary system. Moldavan pumped cells through a capillary tube focused under a microscope for visualization. The invention of photometry allowed the measurement of differentially-stained cells, and Louis Kamentsky developed the first multiparameter flow cytometer in 1965 to identify and count the cancer cells in cervical tissue specimens.

Special Features of Adaptive Immunity
3.4K
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,...

Antigens Involved in Adaptive Immunity
1.6K
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.

Seasoning of Wood
525
Seasoning of wood is a crucial process aimed at reducing and stabilizing the moisture content within the wood to prevent future shrinkage, structural damage, or aesthetic issues once the wood is used in construction. Wood naturally swells when it absorbs moisture and contracts as it dries.
Achieving equilibrium moisture content is the goal of seasoning; this is the point where the wood's moisture content stabilizes to align with the moisture levels of the surrounding environment. Proper...
