An antibody is a protein produced by the immune system to identify and neutralize foreign objects like bacteria and viruses. Antibodies recognize specific antigens unique to their target. Biological therapies for treating diseases employ substances like monoclonal antibodies, interferons, and interleukins. Monoclonal antibodies in particular are increasingly prominent in medicine. They are named using a standardized nomenclature indicating the target, source species, and whether it is a monoclonal, chimeric, or humanized antibody. Common examples of monoclonal antibodies used for treatment include rituximab, infliximab, and adalimumab.

Monoclonal Antibody Nomenclature and Therapeutic Uses
1.
2. An antibody is a protein used by the immune
system to identify and neutralize foreign objects
like bacteria and viruses. Each antibody
recognizes a specific antigen unique to its target.
It stimulate or restore the ability of the immune
(defense) system to fight infection and disease.
Also called immunotherapy or biotherapy/ often
employs substances called biological response
modifiers (BRMs)
Forms of biological therapy include monoclonal
antibodies, interferon, interleukin-2 (IL-2), and
several types of colony- stimulating factors
3. Because of the growing prominence of monoclonal
antibodies in medicine,
The United States Adopted Name (USAN) Council has
provided guidelines for nomenclature In 2011.The
USAN council updated the original guidelines.
The name for a monoclonal antibody is formatted as
PREFIX – TARGET - SOURCE SPECIES – SUFFIX
Prefix: a unique prefix used to identify the product
Target: usually a three-letter identifier for the disease
or target
Source species: 1 or 2 letter identifier of animal
source
Suffix: for monoclonal antibodies is mab
4. Eg- the product rituximab (Rituxan) was the
first chimeric monoclonal antibody approved
in the United States for treatment of
malignancy.
The name can be translated as:
ri = unique prefix
tu = tumor
xi = chimeric
mab = monoclonal antibody
5. NOMENCLATURE FOR NAMING MONOCLONAL ANTIBODY
PRODUCTS
Target Source Species
t = tumors a = rat
li/l = immunomodulators axo = rat-mouse chimer
ba/b = bacterial e = hamster
ci/c = cardiovascular i = primate
fu/f = antifungal zu = humanized
ki/k = interleukins o = mouse
ne/n = Neurons as targets xi = chimeric
so/s = bone xizu = chimeric-humanized
vi/v = viruses,antiviral targets u = fully humanized/human
6. POLYCLONAL AND MONOCLONAL ANTIBODIES
POLYCLONAL -a normal humoral immune response produces
many plasma cells from the selection of many compatible and
useful B-cell lineages producing a pooled polyclonal response
(are antibodies that are derived from different cell lines).
MONOCLONAL antibodies (mAb) are antibodies that are
identical because they were produced by one type of immune
cell, all clones of a single parent cell. This has become an
important tool in biochemistry, molecular biology and
medicine.
Murine Monoclonal Antibodies
In 1975, Köhler and Milstein discovered that murine (mouse)
antibody-secreting plasma cells and immortal murine myeloma
cells could be fused with the benefits of each retained.
Chimeric Monoclonal Antibodies
With the emergence of recombinant DNA technology,
monoclonal antibodies with greater amounts of human
sequences are now being developed and used.
7. Humanized Monoclonal Antibodies
Designed to reduce murine sequence content was the creation
of humanized antibodies. Humanized monoclonal antibodies
typically retain only the hypervariable regions, or
complementary determining regions (cdrs), of a murine
antibody while the remainder of the antibody is human. Thus,
humanized antibodies typically contain only 5% to 10%
murine composition

18. Belimumab is a B-lymphocyte stimulator
(BLyS)-specific inhibitor.
DOSE :- 10 mg/kg IV at 2-week intervals for
the first 3 doses and at 4-week intervals
thereafter. Dilusion in 0.9 % NS
ADR- reactivation of latent infection/prone
for infection due to immunosupresion
19. Atacicept is a fusion protein containing the extracellular,
ligand-binding portion of the TACI (transmembrane
activator and calcium-modulator and cyclophilin-ligand
[CAML]-interactor) receptor, and a modified Fc portion of
human IgG that blocks BLyS (similar to belimumab).
It also contains a B-cell activating factor (a proliferation-
inducing ligand [APRIL]). Levels of both APRIL and BlyS are
increased in SLE patients, suggesting that blocking both
would be more beneficial than blocking either one alone.
The agent would also block both plasma and B cells.
Mavrilimumab, currently in Phase 2b, is a human
monoclonal antibody targeting the alpha subunit of the
granulocyte macrophage colony-stimulating factor
receptor, which inhibits the mononuclear phagocyte
pathway

22. Epratuzumab binds to the glycoprotein CD22 of
mature and malignant B-cells.
Elevated CD22 and other B-cell receptor (BCR)
proteins are associated with SLE. "Epratuzumab's
mechanism of action transfers these BCR proteins
to helper cells called effector cells which reduces B-
cell destruction and epratuzumab's impact on the
body's immune system" via a process
called trogocytosis (is a process
whereby lymphocytes (B, T and NK cells) conjugated
to antigen-presenting cells extract surface
molecules from these cells and express them on their
own surface.)
(Other SLE therapies destroy B-cells which
compromises the immune system.)

activated mononuclear cells .
patients with RA, IL-6 is produced in large quantities
from synovial cells and macrophages, eliciting

33. Signal transduction of interleukin (IL)-6 /IL-6
receptor (R) complex via gp130 and the
mechanism of signal transduction blockage

Anakinra differs from native human IL-1Ra in that it
has the addition of a single methionine residue at its
amino terminus .

occurring IL-1, including inflammation and cartilage
degradation associated with rheumatoid arthritis, by
competitively inhibiting the binding of IL-1 to the
Interleukin-1 type receptor, which is expressed in
many tissues and organs
