53 results about "Immune agent" patented technology

Immunologic agents are drugs that can modify the immune response, either by enhancing or suppressing the immune system. They are used to fight infections, prevent and treat certain diseases. Immunologic agents include drugs used for immunosuppression to prevent graft rejection.

Method for detecting bastard halibut LITAF gene expression by applying reverse transcription-polymerase chain reaction (RT-PCR)

The invention discloses a method for detecting bastard halibut LITAF gene expression by applying reverse transcription-polymerase chain reaction (RT-PCR). The method lays a foundation for studying bastard halibut LITAF gene expression regulation mechanism and immunology function. TNF-alpha plays an important role in the process of immune response and foreign pathogenic bacteria killing, and the LITAF is a transcription factor of TNF-alpha gene and directly controls the expression of the TNF-alpha gene. Therefore, the expression abundance of the LITAF gene reflects the activity of a bastard halibut immune system to a certain extent and can be used as an immune monitoring index and immune agent quality evaluation index in prevention and treatment of bastard halibut diseases. By detecting the variation of the bastard halibut LITAF gene expression quantity, whether the bastard halibut is infected with a disease can be judged in advance and a measure of prevention and treatment can be taken timely so as to avoid unavoidable loss resulting from serious situation; and besides, the advantages and disadvantages of a fish immune agent can be evaluated so as to judge which immune agent has better effect during prevention and treatment of flounder diseases. The invention provides a technology platform for relative quantitative analysis of LITAF gene at the mRNA level.

Cloud-based active immune security defense method and device

The invention relates to a cloud-based active immune security defense method and device. The method mainly comprises the following steps: an immune library management module establishes a mirror imagevirtual machine system which is completely consistent with an off-cloud instance system in an initial state in cloud; the immune cleaning module pushes the in-cloud mirror image system to the out-of-cloud instance system for replacement, the operation and maintenance instance system and the in-cloud mirror image system are kept completely consistent, and meanwhile, inconsistent heterogeneous software is identified; the immune updating module carries out security upgrading on the in-cloud mirror image system; and the immune agent module operates in a hardware remote guidance state in the cloudexternal instance system, receives a cleaning instruction issued by the cloud immune cleaning module, and executes a cleaning action. According to the invention, high security of the system can be realized, risks of continuous penetration and invasion of advanced threats on a system attack surface exposed in a network environment and an operation environment for a long time are reduced, white lists of abnormal programs such as backdoors, Trojans and the like are identified, the system is periodically restored to an initial state, cloud and terminals are isolated in a one-way manner, and active immunization is realized.
