Cryptococcus neoformans is an encapsulated fungus that causes a life-threatening meningoencephalitis in patients with AIDS. Monoclonal antibodies to the capsular glucuronoxylomannan can modulate the infection in mice, but the epitopes on this complex

Passively administered mAbs to Cryptococcus neoformans capsular polysaccharide can alter the course of infection in mouse models. In preliminary studies of passive Ab efficacy, most IgM, IgA, and IgG1 mAbs were protective, but the few IgG3 mAbs teste

Passive antibody administration is a potentially useful approach for the therapy of human Cryptococcus neoformans infections. To evaluate the efficacy of the human immunoglobulin G1 (IgG1) constant region against C. neoformans and to construct murine

As B cells differentiate under the influence of antigen and T cells, they frequently switch from the expression of IgM antibody to the expression of other isotypes. This is accomplished by rearranging the expressed variable region gene to downstream

The antibody responses of BALB/c mice to serotype A Cryptococcus neoformans capsular polysaccharide (CNPS) were compared after cryptococcal infection and immunization with a serotype A glucuronoxylomannan-tetanus toxoid conjugate (GXM-TT). Infection

Mutant mAb with increased Ag binding were generated from a hybridoma cell line, 36-65, that secretes an IgG1,kappa anti-p-azophenylarsonate-(Ars) specific antibody. The mutant antibodies were identified using an Ars-specific ELISA and sib selection s

A V region mutant producing an antibody that had lost the ability to bind phosphocholine was isolated from a hybridoma producing a germline encoded T15 antibody. The mutation resulted in a single aspartic acid to asparagine substitution at residue 95

In the course of an immune response, antibodies undergo affinity maturation in order to increase their efficiency in neutralizing foreign invaders. Affinity maturation occurs by the introduction of multiple point mutations in the variable region gene

We have established B cell culture systems in which transfected and stably integrated Ig constructs spontaneously undergo high rates of variable (V) region mutation. Mutation rates were determined using reversion analysis of an Ig V region nonsense c
