Immunotherapy in cancer: mechanisms of immune response and their place in cancer treatments

hpv linked to bladder cancer Immunotherapy in cancer hpv linked to bladder hpv linked to bladder cancer is a type of treatment discovered in the s. To hpv linked to bladder cancer understand the types of therapies and their indications and side effects, it requires a review of the immune reaction at the time that tumour cells appear and the mechanisms by which the cell manages to fool the immune response and develop malignant tumours, that metastasize and eventually destroy the host.

Cancer immunotherapy involves the use of therapeutic modalities that lead to a manipulation of the immune system by using immune agents such as cytokines, vaccines, hpv linked to bladder cancer therapies and humoral, transfection agents.

We intended to write a review article about immune reactions that take place into onset of cancer and new immunologic treatments developed in last years. Imunoterapia în tratamentul cancerului este o modalitate de tratament descoperită în anii Pentru o mai bună înţelegere a hpv linked to bladder cancer de terapii, a indicaţiilor, cât şi a efectelor adverse, este necesară înţelegerea mecanismului reacţiei imune a organismului hpv linked to bladder cancer momentul apariţiei celulelor tumorale şi a mecanismelor prin care celula păcăleşte răspunsul imun şi dezvoltă o tumoare malignă care în cele din urmă metastazează şi distruge organismul-gazdă.

Imunoterapia cancerului implică folosirea de modalităţi care duc la manipularea sistemului imun folosind agenţi imuni precum citokinele, vaccinurile, terapiile celulare şi umorale, agenţi de transfer. În acest articol prezentăm reacţiile imune care au loc în momentul apariţiei celulei tumorale şi noile tratamente imunologice dezvoltate în ultimii ani.

Immunotherapy in cancer therapy is a type of treatment discovered in the s, with the onset of bladder cancer therapy with BCG and IFN therapy in malignant melanoma 1.

There were discovered various immune therapies such as IL 2 cytokine used in solide tumors like melanoma. A period of decline of these therapies followed, with powerful side effects and minor results in treatments.

Along with studying the mechanisms of immune cells involved in the immune response mediators that cause stimulation or inhibition of the immune response, came the development of  new therapies. Cancer immunotherapy involves the hpv linked to bladder cancer of therapeutic modalities that lead to a manipulation of the immune system by using immune agents such as cytokines, vaccines, cell therapies and humoral, transfection agents 2.

Tumour cells differ from normal cells, by expressing the antigen and biologic behaviour.

Genetic instability is the main generator of the cell cancerous tumour-specific antigens. Recognizing these tumour-specific antigens hpv linked to bladder cancer the cell surface is the centerpiece of immune stimulation 3. Tumour cells express cell surface proteins mutate, fusion proteins or protein aberrantly self expressed, so that the immune system should recognize them. Immunotherapy uses several methods to manipulate the antitumor immune system of the passive immunization with monoclonal antibodies or the induction of systemic cytokine administration of the adjuvant to the tumour microenvironment hpv linked to bladder cancer.

Antigens are harmful substances, such as parts from bacteria, viruses, fungi or parasites and they can also appear on cancer cells. Antibodies are proteins that bind antigens and help, for example, to fight infection.

Antibodies are a key component of the adaptive immune response, playing a central role both in the recognition of foreign antigens and in the stimulation of an immune response to them. It is not surprising, therefore, that many immunotherapeutic approaches involve the use of antibodies. Monoclonal antibodies are made in a laboratory and are directed against a specific protein in the cancer cells, and they do not affect the cells that do not have that protein.

When hpv linked to bladder cancer are given to patients, they act like the antibodies the body produces naturally 5.

Types of monoclonal antibodies Two types of monoclonal antibodies are used in cancer treatments: Naked monoclonal antibodies are antibodies without modification. Conjugated monoclonal antibodies are joined to another molecule, which is either toxic to cells, or radio­active.

University of Texas M. Anderson Cancer Center Summary: Over the next 20 years, the number of new cancer cases diagnosed annually in the United States will increase by 45 percent, from 1. Anderson Cancer Center. It predicts a 67 percent increase in the number of adults ageor-older diagnosed with cancer, from 1 million in to 1.

The toxic chemicals are those typically used as chemotherapy drugs, but other toxins can be used. The antibody binds to specific antigens on cancer cell surfaces, directing the therapy to the tumour. Radioactive compound-linked antibodies are referred to as radiolabelled.

Hpv gardasil adalah the antibodies are labelled with chemotherapy or toxins, they are known as chemolabelled or immunotoxins, respectively. When a monoclonal antibody attaches to a cancer cell, it may accomplish the following goals: It stimulates the immune system to destroy the malignant cell Figure 2.

În ultima perioadă se observă o creştere continuă atât a incidenţei, cât şi a mortalităţii din cauza cancerului. Sunt peste de tipuri de cancer, incluzând tumori solide şi boli maligne hematologice ca leucemiile sau limfoamele. Unele cancere, comune sau rare, pot fi mai agresive, adică se formează, se dezvoltă şi se răspândesc mai rapid decât altele, având un fenotip agresiv.

This makes it easier for the immune system to find and destroy these cells. In present, the monoclonal antibodies that target the PD-1 protein, which are intensely studied, are a good example.

PD-1 keeps the immune system from recognizing that a cell is cancerous, so drugs that block PD-1 - a new class of drugs - allow the immune hpv linked to bladder cancer to identify and eliminate the cancer 6. Prevent cancer cells from growing rapidly.

Growth factors tell cells to grow by attaching to receptors on the surface of cells. The receptor they attach to is called a growth factor receptor. Cancer cells grow faster than normal cells because they can make extra copies of the growth factor receptor.

Monoclonal antibodies can block these receptors and prevent the growth signal from hpv linked to bladder cancer through. Deliver different treatments - radiotherapy - directly to cancer cells.
