From an evolutionary perspective, it is older than the adaptive immune system, the second main branch of the immune system [1]. The major distinction between the two parts of the immune system is that the innate immune system recognizes patterns (that are primarily found in non-self pathogens...
If a pathogen breaches these barriers, the innate immune system provides an immediate, but non-specific response. 如果病原体通过了这层障碍,那么紧接着先天性免疫系统就会产生迅速但非特异性的免疫反应。 LASER-wikipedia2 The parts of the innate immune system have different specificity for different...
Used together with the term adaptive immunity to describe the two functional parts of the immune system. The original strict separation of the two parts of the immune system is currently reconsidered because a deep and intimate interconnection and cross-talk between the humoral and cellular parts of...
There are two main parts to the vertebrate immune system. The innate immune system, which is made up of physical barriers and internal defenses, responds to all pathogens. The adaptive immune system is highly specific. External and Chemical Barriers The body has significant physical barriers to po...
If an antigen gets past these barriers, it is attacked and destroyed by other parts of the immune system.ʺ And, finally cellular barriers comprise various cells which attach the antigens. These may include but are not limited to the following: • B Cells or B lymphocytes • Dendritic ...

Today, however, synergistic and interfacing parts of the two systems have been appreciated. There are now several mechanisms known by which the innate immune system instructs and directs adaptive immune responses [1]. Understanding this, and the distinct responsibilities of the innate immune system,...
The immune system of vertebrates has been conceptually divided into two parts, innate and acquired immunity. There are many distinguishing features of the two systems, but the essential difference is genetic. The recognition proteins of the former are encoded in the germline, having evolved in ...
