We herein detail the methodology followed to compare protective efficacy and lung immune response induced by intranasal and subcutaneous immunization with BCG in mouse model. Our results show the benefits of pulmonary vaccination and suggest a role for IL17-mediated response in vaccine-induced protection.

What is the Immune System?

Overview The immune system comprises diverse biological structures and processes that protect the body from disease. These processes can be classified into innate and adaptive immunity. To work effectively, the immune system needs to detect pathogens by distinguishing the body’s own structures from foreign elements. If this determination fails, autoimmune diseases occur in which the immune system reacts against the body’s own tissue. The Innate Immune System Acts Fast and Non-specifically

Zones of Protection

In power systems, the entire setup is divided into protective zones to isolate faults and protect the rest of the network. These zones include generators, transformers, buses, transmission lines, distribution lines, and motors. Each zone can be visualized as a separate room in a house, with each room protected by its own circuit breaker. Protective zones are defined by closed dashed lines, containing one or more components. A key characteristic of these zones is the strategic placement of...
FAQs
Skin and mucous membranes act as early physical barriers that reduce opportunities for pathogens and foreign substances to enter tissues. If a threat breaches these defenses, inflammation contributes to the body's response. Together, these mechanisms provide initial protection before antigen-specific B and T lymphocytes are involved.
Innate defenses respond through barriers and inflammation, whereas adaptive immunity relies on antigen-specific B and T lymphocytes. This distinction matters because the two branches contribute differently to protection: innate mechanisms provide early defense, while adaptive cells participate in eliminating particular threats and generating immunological memory. Biology uses this relationship to explain coordinated responses to infection.
Antigen specificity allows adaptive immunity to direct B- and T-lymphocyte activity toward particular foreign targets rather than relying only on general barriers or inflammation. This focused response supports elimination of threats and can generate immunological memory. In biology, that combination helps explain why adaptive mechanisms are important both during infection and in vaccination.
Vaccination applies immune protection by presenting antigens in a way that prepares a protective response without causing the target disease. The antigen exposure engages the adaptive side of immunity and supports immunological memory. As a result, vaccination is studied as a preventive strategy that uses biological defense mechanisms while avoiding the disease it is designed to address.
Research on immune protection extends beyond infection itself. It helps investigators examine autoimmunity, immunodeficiency, and therapeutics designed to influence immune responses. These areas connect basic biology with questions about why defenses fail, become harmful, or can be harnessed in treatment, making immune protection relevant to both disease investigation and therapeutic research.
Immune protection can have two biological outcomes for tissues: it can limit harm from pathogens, or the response itself can contribute to disease. This balance is a major reason biology studies immune responses in relation to infection, autoimmunity, and immunodeficiency. Examining both outcomes helps distinguish beneficial defense from responses associated with harmful effects or inadequate protection.
