Likely #neutrophils since they're the predominant leukocytes in our blood and also move faster than the others

Neutrophils recruited to immunization sites initiating vaccine-induced antibody responses by locally expressing BAFF Neutrophils played a key role in the innate immune responses. Less is known about whether and how the neutrophils recruited in the immunization sites …

🔥 #Neutrophils in Vaccine Responses
- Neutrophils are crucial for effective vaccine responses, acting as early responders that help initiate and shape adaptive immunity, particularly antibody production,

#Neutrophils employ several direct & indirect mechanisms to limit viral spread
- Viral Clearance as they eliminate viruses through #phagocytosis (ingesting virions) & degranulation, which releases antimicrobial peptides like α-defensins and cathelicidins

providing critical early protection while also driving severe tissue damage if overactivated & are the most abundant #leukocytes in human circulation & #Neutrophils are among the first immune cells recruited to sites of infection, including those caused by viruses.

#immunosky
#Neutrophils are the first responders of the #innateimmune system recruited to sites of viral infection. Traditionally known for fighting bacteria, they are now recognized as a "double-edged sword" in viral infections,
