Vaccines

Vaccines

Vaccines are among the most effective tools in preventive medicine, designed to prepare the immune system to recognize and combat infectious agents. By introducing antigens—substances that the immune system identifies as foreign—vaccines stimulate an adaptive immune response that leads to immunological memory. This immunological memory enables the body to mount a faster and more effective response upon future exposures to the actual pathogen.Vaccines can be categorized based on the type of...

Cancer Vaccines

Cancer Vaccines

Cancer treatment vaccines are a rapidly evolving field that offers a promising approach to immunotherapy. Unlike traditional vaccines that prevent diseases, cancer treatment vaccines are designed to treat existing cancers by stimulating the immune system to recognize and attack cancer cells.
Cancer vaccines come in two categories: preventive (prophylactic) and treatment (active). Preventive vaccines, such as the Human Papillomavirus (HPV) vaccine, protect against viruses that cause certain...

Vaccine Production

Vaccine Production

Vaccine production involves a sequence of upstream and downstream processes to generate a safe and effective immunological product. It begins with cultivating microorganisms, such as viruses or bacteria, to obtain antigenic material. For viral vaccines, mammalian host cells are grown in bioreactors and subsequently infected with the target virus. The virus replicates within the host cells, which are lysed to release viral particles. This lysate is then clarified through filtration or...

Poliomyelitis

Poliomyelitis

Poliomyelitis is caused by poliovirus, a small, non-enveloped, positive-sense RNA virus of the Picornaviridae family and Enterovirus genus. Transmission occurs primarily via the fecal-oral route, often through ingestion of contaminated water or food. The virus initially replicates in the oropharynx and intestinal mucosa, particularly in lymphoid tissues such as the tonsils, Peyer’s patches, and regional lymph nodes. Primary viremia follows, allowing dissemination throughout the body.In most...

Microorganisms in Medicine and Therapeutics

Microorganisms in Medicine and Therapeutics

Microorganisms play a fundamental role in vaccine development, gene therapy, and therapeutic production. Their biological properties are harnessed to advance medicine and public health. Beyond immunization, microorganisms contribute to gut health, antibiotic synthesis, and genetic disease treatment.Live Attenuated and Inactivated VaccinesLive attenuated vaccines, such as the measles, mumps, and rubella (MMR) vaccine, utilize weakened forms of pathogens to closely resemble natural infections.

Background:

Nucleic acid vaccines, including DNA and mRNA, represent a recent advancement in vaccine technology.
Early research demonstrated that intramuscular injection of DNA vectors leads to in vivo protein expression in muscle cells.
This in vivo expression capability is key to generating immune responses against encoded antigens.

Purpose of the Study:

To explore the potential of DNA and mRNA as vaccine vectors.
To understand the immune responses elicited by nucleic acid-based immunization.
To compare the advantages of DNA injection with other vaccine technologies.

Main Methods:

Utilizing plasmid DNA expression vectors or mRNA encoding reporter genes for intramuscular injection in animal models.
Monitoring in vivo protein expression in muscle cells.
Assessing both humoral and cell-mediated immune (CMI) responses, including cytotoxic T-lymphocyte (CTL) induction.

Main Results:

Demonstrated efficacy of DNA vaccines in animal models for viral diseases.
Confirmed in vivo protein expression following intramuscular nucleic acid injection.
Showcased the ability to induce both humoral and CMI responses, including CTLs.

Conclusions:

DNA and mRNA vaccines offer a promising platform for inducing comprehensive immune responses.
The in vivo expression capability of nucleic acid vaccines allows for the induction of CTL responses, which are often lacking in other vaccine types.
DNA injection presents potential advantages over certain existing vaccine technologies due to its ability to elicit both humoral and cell-mediated immunity.
